Lots of aesthetics; for apps with searchpaths listed multiple times (like /pandora/apps), don't pull the same pnd in multiple tiles; for conf overrides, also look in /pandora/appdata/mmenu (normalyl just /pandora/mmenu); for sorting, sort upper/lowercase app names together H h I i not H I h i); when using keyboard to jump to app, repeat hitting key to cycle through apps of same starting character
