Please, please, please stop making everything an "intuitive" icon with no easy way to get text to tell you what a button is supposed to do.
Not everyone is constantly using the same program and wants to just start guessing what menu icons do in the hopes of figuring out over time how to work the damn app!
That's my biggest issue with these minimalist pretty designs, half the time you can't figure out what the stupid menu options actually do, let alone find the one you figure should be in there but who knows what it looks like. Don't get me started on mysterious gestures being required for an app.
This lack of basic usability is one of the two major reasons Apple mobile products are banned for technical support in my family now. The other is the walled garden, but I digress....
