Deleting is definitely the feature I'd most like to have.

I don't generally love the idea of taking over right click behavior, but I've pushed out a patch to allow removing elements using right click. This is an admittedly poor solution (especially for lines, as they are very small click targets). Hopefully I'll have a chance to develop a more robust way to delete elements such as the box method that you described.

Back when I used to work with cad software, you could select elements by using a drag box, but interestingly there were two kinds. I'm gonna call them inclusive and exclusive because idk what they're actually called, but dragging the region one way created a selection of contents completely contained in the region. The other way would create a selection of any object partly contained in that region. It was an interesting way to deal with large amounts of intersecting objects and selecting the correct one

Awesome! Another option if you don't want to take over right-click behavior could be shift-click (holding shift and clicking), or similar.

I like that idea. I've changed to using shift for deletion. I've also enabled deleting on both mouse clicks and movement, so you can hold down shift and wiggle the mouse around like an eraser. This makes it much easier to delete lines.

Thanks! I like that you can delete on mouse movement -- I think it's actually better and more intuitive than my original suggestion.

It seems that vertical lines can only be erased when mouse moves vertically or almost vertically while holding shift.
