Arrows

[nanvenomous]

Is your feature request related to a problem? Please describe.
I find myself frequently needing to draw arrows like so:

I think that's a pretty important part of prototyping/ideating systems.
Right now an arrow can take 3-4 steps.
I'd be really curious if others draw arrows as often as I do.

Describe the solution you'd like
I'd like to be able to switch to arrow mode and then draw an arrow (possibly one including a bend) in one step.
An arrow with a bend usually looks like:

Describe alternatives you've considered
Unfortunately I don't know the problem space quite well enough to suggest alternatives. In diagramming I generally use arrows to turn a line into a vector or indicate flow from one box to another.

Additional context
I'd also be excited to take this on, but I'm having trouble understanding the event loop of the application & subsequently breaking down the problem.
