In the left-side bar, where the files/folders are displayed, it's possible to right-click on a folder and, from the context menu, click "Find In Folder...". This works great, except when you already have the find_in_folder panel open.
To reproduce this:
1) Open sublime
2) Make sure you have TWO folders in the sidebar.
3) Right click folder (1) and click "find in folder"
4) The find-in-folder panel should appear at the bottom of the application
5) Right click folder (2) and click "find in folder"
The panel will dissappear. It seems to be toggling instead of coming up with the new "In Location" param set correctly.
Running on Mac OS X 10.6 with Sublime [beta] build 2126.
Thanks for sublime btw. It rocks!
