looks like some kb functionality changes in iOS7
this would increase speed, save space on the ipad, and be more green in general.
perhaps it could be in a performance section of preferences, or "mobile performance" as it would be most useful on the ipad/iphone, many full Mac install users would not care or prefer to have all the files.
"ignored filetypes (Global)"
maybe an "Other" or "Experimental" tab for features that have no home yet.
ill think more on this, but good idea.
could just be a * before the title on the/each tab to indicate unsaved.
(i believe this is what np++ does)
