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

Smart tabs for code indentation
The best thing about this is that it survives being opened in a variety of editors without looking like garbage.

Open, edit, validate, package EPUB format
- Open and edit within an EPUB archive.
- Package a project folder as an EPUB.
- Validate EPUB package using epubcheck. (lowest priority)

Allow user to specify line-ending type

'Open with...' from the sidebar
Textmate, Coda etc all have a very useful option to open the currently right-clicked file in another app. This would be really useful to me because I edit CSS in another app & currently have been using the Finder to open the files. If I could do that from within Sublime it would be brilliant.

Add a history of editions spots
It's very handy since you do a lot of back and forth while editing code, and you don't have to 'remember' to set a bookmark.
it's hard to do since you have to decide what to do in cases such as file and lines deletion.

Faster Startup / Close = Hide

Document history tree feature like in E-TextEditor with Visual history navigation.
If you look at the link I include below you will see that it has a visual panel that comes up and lets you click on the different changes and branches and see what you had where. This allows the user to easily pluck deleted code from the history and add it back in without all that undoing and saving a bunch of other snippets into open blank document windows that you might have to do now.
Also, being able to use a diff tool on this would be even better so that you can see the differences between two different points in history or between the current version and a different point in history.

Allow "Open Files" to be docked to top of sidebar
This would make it a more complete replacement for the tab bar, which I would prefer to hide, as vertical screen space is at a premium compared to horizontal space with widescreen monitors. And I'm the type of person that likes to see as many lines of code on screen as possible.
For a good example of this type of functionality, take a look at Espresso 2's UI (http://macrabbit.com/espresso/). Or even Chocolat (http://chocolatapp.com/).

Preview .tm Themes
A preview, while moving my mouse , or up-down keys on the menu items would be very helpful for those who would like to play around with themes like me..
