You've already added a menu item to search for documentation on a highlighted bit of code, and it occurred to me today that it'd be nice to be able to add 2-3 scripts to that menu myself, for certain common operations I do on highlighted words and text. Obviously there's limited space there, and I'm not sure what sort of a nuisance it would be to add this functionality, but I'd sure use it, both in Pythonista and Editorial.

I agree with sidewinder — no (*&$#%#$ in-app purchases, please. The practice is repulsive. The app is hardly expensive in the first place, given what it does, and numpy will definitely attract new users.

Any chance for linear and radial gradients in the canvas and scene modules in some future update?

There are ways to do this in pure python, but it ain't speedy.
