Using latest PHPStorm (7.1.3) on Ubuntu 12.04
Just checked my options: having 10 tabs/files loaded and shown on screen, when loading another one, PS should replace the LRU (Least recently used) one with that file.
However, and this is pretty annoying, PS removes the MRU (Most recently used!)... So when switching between two files several times, I end up having to click in the file list all the time...
Did I miss an option somewhere? Is it a feature? A bug?
