Promising

Very nice concept and quite well done.
But it is annoyingly cumbersome to edit certain parts of the formula. There is an eraser missing badly. You have to cross out what you do not want but of course most of the time your crossing out is misinterpreted as it could be a math symbol. This takes up most of the time during input very disappointing.
Add an erasing option instead, that is simple and not ambiguous.
Exporting the formulas is a pain too. You have to go through a dialog an at least 4 clicks just to copy your formula. In the top line there is PLENTY of space to put a button for copying with direct access.
Even more interesting:
This tool would be great as a keyboard to create and input formulas everywhere.
