If a < b < c, when we subtract the region [a,b] from the region [a,c] the result is [a,a] (or empty) and not the expected [b,c].

>>> view.sel().clear()
>>> view.sel().add(sublime.Region(0,10))
>>> view.sel().subtract(sublime.Region(0,5))

Today when Sublime saves a file and encounters a character that can't be encoded in eg ISO-8859-1, it automatically converts it to UTF-8 (and informs you with a popup dialog with just one option - OK). This destroys the file (UTF-8 encoding is in many cases non reversible), so it would be nice if this instead was a question. It would also be very nice if Sublime could highlight or somehow search for unencodable characters (characters like non-braking space is _very_ difficult to distinguish from a normal space).

 With the growing number of community packages, each one adding their own keyboard shortcut, we're to a point where we can run into conflict. May it be internationals keyboard configuration, shortcuts overwriting others plugins ones, etc.

I think we should be able to disable/protect some specific keyboard key from being used. This would allow the user to prevent packages from removing some important characters or system wide shortcuts.

Is there a keyboard shortcut or plugin to search for other occurrences of a word under cursor, like vim * and # commands?

I prefer to display open files in the sidebar instead of in tabs. It would be great to have an option to show open files inline in the folder view rather than a separate list. I think of my files grouped like my folder structure and frequently switch between files in the same folder. The open files list is a jumble of files. I can drag them around but that's more work—I already organized the files into folders. Along with this when opening a project, folders containing open files should be expanded by default so the files are visible. Please keep the one-click to display feature for open files though. In fact, I suggest it be the default behavior.
