A semi-intelligent case-sensitivity mode for searches as option, like in Emacs, where, if I type the word to search in all-lowercase, it will search case-insensitively and as soon as I type something containing uppercase, it will search case-sensitively exactly for what I typed.

There you can see, how it could look.

I was searching for a ftp/sftp plugin just like Zend Studio 5.5 / Notepad++ etc. I stumbled upon this thread: http://www.sublimetext.com/forum/viewtopic.php?f=4&t=5846

It would be awesome if you could drag/drop to reorder files and folders in the sidebar! 

Contextual highlighting and syntax style for PowerShell and VB Script.

I've got many Situations where i want to insert Images to my Project, when i select an Image i get the preview of the includet data as Text. It would be nice, if you provide the functionality to get a preview of images. Maybe you use the file extention as trigger, or you read the file header to check if a different preview is needed.

When right-clicking on a file tab, it would be useful to have "Open Containing Folder" like in Visual Studio

You are now able to fold functions when there's more then 1 line of code.
It would be nice to also fold on-lined functions

Finding text inside my selection is never what I want to do, and yet it happens by default if anything is selected.

add prolog syntax coloration,
this feature would be awesome, just like the rest of the editor! =)
