After a long wait, we have in our clutches a Leopard-friendly (actually, Leopard-only) build of Letterbox. It also rolls in some other nice improvements. Full deets below the fold.

![[DOWNLOAD]](/projects/images/badges/download.gif)
This version adds Leopard compatibility, a spiffy auto-updating mechanism, a simple preference pane, and menu items for quick switching. It does not yet have a two-line column, which will wait for another day. I’ll probably push out a very minor update by today or tomorrow, just to test the auto-updating mechanism. Any and all feedback is appreciated.
Also: Some of you are probably making use of Dane’s Harnett’s excellent work on WidescreenMailPlugin. I welcome cross-fertilization of ideas or even code. Feel free to let me know what’s working better in one or the other, and hopefully we can keep making our Mail.app experience a little more pleasant for everybody. This go-round I really will make Letterbox’s source code, as well as the underlying improvements to the Mail plugin template, available.
I do suspect, though, that it’s a good idea to have only one or the other enabled at any one time. You can use the MailPluginManager application included with Letterbox to temporarily disable WidescreenMailPlugin — or Letterbox — for the sake of testing.
cheers,
Aaron
Full changelog:
Letterbox 0.22
Released Dec 04, 2007
First public release for Leopard.
Details:
Added preference for hairline or normal divider.
Actually runs on PPC machines, those poor red-headed stepchildren.
Choosing a preview pane position in the menu now also updates the sticky preference. Let me know if this is sensible.
Dropped the “Left” preview pane position until its bugs can be worked around.
Possibly still some weirdness in there, especially around closing windows. Lemme know!
Letterbox 0.21
Released Dec 04, 2007
First limited beta release for Leopard, with support for auto-updating and a preference pane.
Details:
Minor bugfixes to prep for limited beta.
Left-side position can cause extreme weirdness.
Letterbox 0.20
Released Dec 03, 2007
First release for Leopard, with support for auto-updating and a preference pane.
Details:
Leopard compatible (in fact, Leopard-only).
Preference pane to fiddle with options.
View menu item lets you switch the preview pane instantly between right, left, and bottom.
Added options for alternate-row coloring and horizontal divider lines.
No longer eats your children.
Annoyances with searches throwing the column width akimbo seem to be resolved; this is Apple’s doing, not mine.
Uses a wider divider between the message list and preview pane, with a gradient modeled after the builtin Mail.app divider.
Sometimes causes the dead to reanimate.
Outlook-style two-line column put off for future release.

Agh, that download link is not working. 502 error.

Can’t seem to get the plugin to work. I click on the bundle to install and instead of getting the install page (step two) I get a mail message opened with letterbox plugin as an attachment.
thanks in advance for any help

Connie, try dragging the .mailbundle directly onto the MailPluginManager application — that should get the installer working more happily.

Aaron, I don’t seem to be getting a “Subject” column in Leopard running .022…
Not even an option to turn the subject column on…
I am likely overlooking something insanely obvious.
Thanks,
-Eli

Eli — that’s likely due to this Widemail bug. You’ll have to reinstall Widemail, enable the Subject column, then remove (if you so choose) Widemail again.

Aaron,
Can’t get Letterbox to work without creating major problems with Mail. Here are the issues I keep facing once Letterbox is installed:
Any thoughts on what may be causing this behavior? Using Letterbox vs. 0.22 for Leopard, Mac OSX 10.5.1, and Macbook Pro.
Thanks,
Jeff

If I could only merge the two plugins, Widemail, and this Letterbox plugin, I think I would be completely satisfied. I think you’ve got the backend of this plugin integrated better, but the fact that yours is still missing the customizable 2-line integration really sets it back on the front-end. You CANNOT display all you want on one-liners with the preview on the right. So I know you’re working on that, but until that’s in, Widemail is probably going to have to be my temp.
Otherwise, the thing that Widemail does well is the customizable 2-liner interface. Drag-drop method is great, it just isn’t perfect yet. If you could build upon this, allow more options to add to Widemail’s list of 2-line options, but I think at this point getting the 2-line feature to look more and more like Entourage’s method would be perfect. Having the column separate emails by day with a “bar” marking the day like in Entourage would be extremely handny, as well as being able to have the options chosen justify to BOTH the right and the left separately would be nice, as it makes the most sense as implemented in Entourage. Entourage has this whole thing integrated very nicely, and I believe it to be a perfect model at this point.
I know reading this, most of you are probably like, “why not just use Entourage?.” Frankly, I’m tired of Entourage, I’m tired of Microsoft’s lack of support (it’s still PowerPC and it’s slow and unstable now), and I would much prefer to use Mail/iCal/Address Book despite the tight integration of the three features in Entourage. Plus it would save me $400 on the upgrade cost if I can just use built in apps the way I want them to work.
So otherwise, thanks for the great plugin and keep up the hard work!

This is for Jeff Roberts - try quitting mail before installing the plugin. I had the same symptoms as you and this caused it to run fine. Casp

When I installed version 0.16 under Tiger, it was active for all users. In contrast 0.22 under Leopard is active only for me, and not for any other users. I have an administrator account. Is there a way of activating letterbox for all users? Certainly the installer does not ask whether the installation should be for all users or not.
Otherwise, thanks for the great plugin.

Charles — you’re right, the installer simply installs for the current user. To activate it for all users, just move the Letterbox.mailbundle file from ~/Library/Mail/Bundles to /Library/Mail/Bundles (creating the folder if necessary).

I absolutely love this program! The prefs are a big plus - love the line dividers. Keep up the great work!
