Using a case sensitive FS, When creating, then renaming a file, the file gets renamed, but this is not reflected in ST2 UI.
This creates numerous issues:
You can then open the wrong file casing in the side bar.
If you save that file again, it is created with the wrong casing, resulting in two files.
Sometime it won't open a file the the UI has the wrong casing for.
It requires a restart of ST2 to get the correct casing for files back.
This can easily be tested by opening a folder on a case sensitive disk image on OS X.
