1,2,3,4,5 shortcuts for tools!

Hey! Great app! So happy you made this.

Love the shortcuts, it'd also be cool to have (video game style) shortcuts just based on the position of the tool,

so 1 - select, 2 - arrow, 3 - rectangle, etc.

feel free to close if you hate the idea, but I tried this instinctively

I second this idea. Would definitely use.
