A list of methods ordered by name, or by lines
Did a quick mockup of what could be done:

The outline could be configurable by language using plugins with basic regexp rules to find function names and attributes

Many Windows users have Explorer replacements such as Total Commander, XYPlorer, Directory Opus, xplorer2, etc. These usually replace explorer.exe via changing the Folder handler in the registry at: [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\]

However - even when someone has a custom folder handler setup - SublimeText currently always opens a folder via Explorer.exe and not through an os-specific way. An alternative to fix this that I have tested is to use os.startfile("C:\folderpath"). For example the following will respect the user's custom directory handler:

import sublime, sublime_plugin, os

class OpenContainingDirCommand(sublime_plugin.TextCommand):

    def run(self, edit):

        branch, leaf = os.path.split(self.view.file_name())

        os.startfile(branch)

So please use os.startfile(dirpath) for things such as "Browse Package".

Many Linux desktops and applications have switched to GTK+ 3, it would be great to update Sublime Text to GTK+ 3 to offer a more coherent visual experience.

It would be really nice to have the option to search

in the code only,

ignoring any match that comes from the comments.

It would be great if TAB would cycle through completions when pressed multiple times. I never need a non-leading tab and would prefer the behavior like in Textmate.

So that we can definitely forget about vi and emacs, and use Sublime Text everywhere

The YAML syntax highlighter doesn't follow lines terminated with slashes, surrounded with single-quotes, or unquoted.  

Additionally, tab indentation is an error according to the YAML spec, so the default should be to use spaces.

Example data in screenshot:

If I have a 'word' selected, it would be great if that selection appeared in the Ctrl+P thingy when I hit Ctrl+P. If the text in the pane were selected, then I could just start typing if it wasn't what I wanted (and hit right arrow to go to the end if I wanted to edit it)

A developer signed executable for Mac and Windows would not be terribly expensive for you to get and would allow your application to run on systems with more stringent security against unauthorized installers enabled.  I learned about this editor just after installing Mountain Lion and so far what I've learned is that Gatekeeper works.  On my domain managed windows desktop at work it was also blocked as "unknown" publisher.

When I have two columns open in split view, clicking on the file's tab in either split window should give focus to the appropriate file. Instead, we must currently click on the file buffer itself to switch between splits.
