 A mostly functional, but incredibly basic text editor.
 ### Features
 - Cursor-less text editing (remember how Minecraft book writing used to feel like? Yeah. That.)
-- Save file - You have to type in the filename and extension yourself. The good news is the "." key works on this screen.
+- Save file - You only have to type the filename; the ".txt" extension will be automatically added.
 - Open file - You can select from a list of files in the SD card. Still no line scrolling here, so only the first 7 files will be visible
 - If you open a file, the save menu conveniently fills in the filename for you, so you don't have to write it again to re-save.
