Instead of having a set of predefined layouts to choose from, a more flexible and fundamentally simple way (from the user's point of view) would be to have actions for horizontal and vertical splitting.

This is a repost from PrideChung in the forums under the topic suggestion about handling shortcut conflict .

Please add Puppet language syntax support (similar to Ruby but not quite)?

I would love to see support for multiple projects in a single window.

Personally I find the one-project-per-window approach difficult to use. Especially when I am working on two related projects, having access to multiple projects' files in one consolidated list would be very helpful.

How I imagine this working is splitting the sidebar up into collapsible top-level project groups:

Foo Project 1
    OPEN FILES
        (Foo Project 1's open files list)
    FOLDERS
        (Foo Project 1's folders)

Foo Project 2
    OPEN FILES
        (Foo Project 2's open files list)
    FOLDERS
        (Foo Project 2's folders)
etc.

Clicking on an open file or folder would switch the tabs shown in the current window to the corresponding project's open tabs.

With drag and drop support in the sidebar it would be easy to move open tabs and files between projects. 

This method could also help with ST2's problem of adding random unrelated/one-off files to the project that happens to be open/focused. By optionally having a 'Loose Files' project in the sidebar, opened files that are outside of any open project's folder scope could be automatically (or manually) put there without opening another ST2 window.

Allowing both multiple windows and multiple projects per window (and remembering these between sessions) could work well for certain styles of workflow as well. Some 'search in all this window's projects' function akin to (or replacing) Ctrl+P would also be dandy.

I'm currently using Dropbox to sync "Packages" and "Pristine Packages" between Mac OS X and Ubuntu via symlinks, and it seems to be working like a charm.
Of course I'm not syncing the session because it would make no sense.

If I do a find and replace across multiple files in a directory or selection and want to undo, ctrl+z, should undo the change in ALL files.

You've completed one part of that by making sublime. I've fallen bracket over function for Sublime 2, broke up with my previous editor, and never looked back. I paid in like 1 week of using the trial. The ability to run on my Mac Mini, Linux Laptop, and my PC computer all the same really makes this a beautiful addition. I'll gladly support this program. Thank you for making awesome happen.

Build in the capability to set the backgrounds of gutters, the folder tree, and backgrounds seperately.  A good discussion on the soda project. https://github.com/buymeasoda/soda-theme/issues/49

It would be very handy to have a way to close all open tabs with one command. Maybe Cmd/Ctrl-Shift-W instead of Cmd/Ctrl-W?
