Sublime Text 2 is a text editor for OS X, Linux and Windows, currently in beta.

Autosuggest for variables containing dashes doesn't work
The 'extract_completions' method seams to have a bug when it comes to variables that contain one or more dashes.
Testcase
$button_color_main: #0f0 /* works as expected */
$button-color-secondary: #f00 /* will auto complete only the word '$button' */
The bug is double checked and confirmed, more here: https://github.com/alienhard/SublimeAllAutocomplete/issues/18

'Show build results' doesn't make sense if already shown (turn into 'Show/Hide' and move to View menu)
First, Tools->Build Results->Show Build Results menu item does nothing if those are present. It should change name to 'Hide Build Results'.

Style Token feature from Notepad++
A way to highlight certain pieces of text with different colors. Like the current highliting when you find a word, but I can assign permanent colors to the text.
Very useful when tracking variables / file logs through large files.

Sublime is extremely slow
What I mean is when I type text, it is very slow to appear and it appears in bursts. Same thing with erasing and scrolling. Kind of like network lag in video games. This is on a fresh install on Ubuntu 12.04 with no plugins. The system is fast otherwise with a fast cpu and 16 gigs of ram.
After I erase all the settings reverting to "fresh install", it is fast for about two minutes on a normal text file and then becomes very slow again.

Textmate style word completion
"TextMate has a simple yet effective completion function on ⎋ (escape). It will complete the current word based on matches in the current document. If there are multiple matches, you can cycle through these by pressing ⎋ continuously. It is also possible to cycle backwards using ⇧⎋.
The matches are sorted by distance from the caret, meaning candidates which are closer to the caret will be suggested before candidates farther away."
This is an improvement over the current tab-completion because:
- The tab key is also used for tabbing.
- It cycles continuously.
- It is based on nearest matches.

Use Textmate fold markers
Textmate grammars have specifiers for where possible folds should begin and end (foldingStartMarker and foldingStopMarker). It would be excellent if these were supported in Sublime Text 2 to make it easy to fold functions etc.
