Yeah, I like the idea. Others have mentioned this (holding e) to me as well.
The only thing is that we already have hold E and hold D functionality working. Holding E gives you the Eraser settings and holding D – the Draw Settings. When you let go, the box goes away.
Do you like this way of getting to the settings easily and quickly? Maybe we could do both somehow? I mean, if you hold and draw/erase right away it works as you say – but if you wait for the settings to come up without putting the pen to the surface it goes to settings mode? Of course this could turn out to be too much and too complicated to easily figure out and work with. But maybe it would be worth testing.
What do you think Kristian? I would love to hear if you could elaborate further? Maybe you prefer to have the settings come up in a completely other way? Please let me pick your brain! 😉
