Hey @mlisthenewcool 👋 , interesting use cases! I haven't seen these discussed before in the visx community, but they're clearly valid / common vis use-cases.

I think for the first case (multiple brushes), you could probably implement it already using the existing Brush component. You would need to handle the ctrl key listeners yourself, but then there's nothing stopping you from rendering multiple brushes and keeping track of their selections.

For the second case (non-linear), we could probably build something like that pretty easily on top of @visx/drag since it allows you to draw arbitrary shapes (see this demo). Building that as a re-usable new component in @visx/brush would be pretty great so others don't have to manage all of the complexity.
