I didn't see a "Favorites List" or "Quick Open" plugin in Package Control, so I went ahead and made one. You can add a list of files in the settings file, and then hit a keyboard shortcut to open a panel that allows you to select one of them. Should work fine with ST2 and ST3.
Lol, I saw that after I wrote it. It didn't take long, and it was fun, so it was still definitely worth it
Just in case you want favorite folders instead of favorite files, you can also try github.com/facelessuser/FuzzyFileNav. Though you could always just extend your plugin if you want Oh and you may want to make a note, "ctrl+alt+shift+p" overrides a default binding in linux and windows systems. Not that you are going to completely avoid these issues, but you may want to make a note of it in your readme (since it's a default binding).
