Serial log on the browser. Maybe somehow limited to use less ram (updates when it's open, doesn't save anything to device itself, like terminal would on windows for example.)
files, especially images from externals servers. So you don't need to save them on the device. (also loading them could be faster) And this for imagebuttons too.
Reboot for the settings menu.
Ability to view code of default program outside editor. Now if you open from file manager it's same as running it. So if your editor becomes unresponsive (like i have sometimes problems at getting timeout when loading longer programs) you could get your program safe on your computer.
Something now in the beginning. Thanks.
