Some more items to discuss... (low prio!)
_Detect filetype from first line_ Since v1.68, SciTE can detect language of file from initial #! line.
This sort of detection would also be cool for <?php or other tags. The detection should take place when creating a new file and when opening a file with an unknown file extension.
_File browser in sidebar_ With a shortcut to open the location of the current file.
_Hide empty symbol types in sidebar_ If a symbol has no declarations, don't show the label. This keeps the symbol sidebar clean.
_READ ONLY_ If you don't have the permission to save the opened file, indicate it in the title like "*file1 - READ ONLY - /usr/bin - Geany" and upon save (ctrl-s) open the "Save as..." dialog, instead of the tiny statusbar notification.
There was something else, but I can't remember it... Ah well, maybe I'll even post a pt. 3 sometime!
Cheers!
-a happy Geany user-
