Any screenshots of that file listing/execution, and what kind of built-in tools were you planning?
Once I work out all of the kinks in file listing and execution, I'll post some GIFs of it functioning correctly (hopefully ).
I have a few tools in mind, but the one that seems the most interesting would be some sort of macro scripting language. These macros could be set to on key shortcuts (such as on-math), so you can activate them at any time.
If you have any other questions, please let me know!
