Way back in 2006 – after the excitement of the Midterm Elections and before the launch of the Wii – Hetima wrote MissingDrawer, a plugin for the oft-mentioned TextMate that took the standard-issue OS X drawer used by TextMate project file lists and turned it into an Xcode-like pane embedded in the edit window. It was lauded by many as a major improvement of the TextMate UI, but has gone pretty much untouched since then, perhaps because it was good enough for most users to begin with. But Jannis Leidel saw room for improvement.
The new MissingDrawer builds off of the original, adding some aesthetic UI tweaks along with some usability polish. On the aesthetic front, it increases the line height of the file list, shrinks the project buttons and tweaks the file list frame. A new resize method accompanies the Mail.app-style resizer handle and the position of the splitter pane is saved automatically now. And lastly, the panel now hides when using the Show/Hide Project Drawer menu item or shortcut.
You can download the 2008 MissingDrawer (including source code) at Jannis' site, and installation is a couple of double clicks away. TextMate users who liked the first version of the plugin will surely appreciate the touch-up. I know I do.
