run app, recorder and alarms

I guess one option is to do like we do when notifications arrive - to buzz the watch and flash a notification when not on a clock, but to only actually go to the alarm if you tap it.

Otherwise I guess the run app could save its state when it exits, and could resume, but it's all extra complexity and stuff to go wrong.

is it possible to enlarge them and maybe give them a different color?

They're based on the current theme, so you can just change the theme... But the button text is part of the built-in menu system - it could still be changed by doing something like https://www.espruino.com/Bangle.js+Modification though.
