Yes, this would be very cool though there's also a "Special Write" mode used to draw velocity curves. That 3rd mode may distract from the point made here so I'll leave it to Rui to chime in. On the surface though, Select and Write are by far, the most common modes used (of the 3) and therefore, would make for a really useful toggle. I'd just add that if we're going to explore this idea, may as well go all the way and alter the visual appearance of the cursor itself to reflect the current mode. Something like a pen when writing and a lasso (maybe) for Select.
