Select all items of type

Miro has a very useful tool to be able to select an entire area and then only select items of a type.

Specifically, this is really useful for selecting an entire board, then filtering to just the stickies on top of a board to move them and leave the image or diagram underneath untouched.

This would be great to add to FigJam for feature parity, and I really miss it coming from Miro.
