Online Interactive Borderlands Skill Trees: need way to remove points

A nice tool for planning builds but there’s no way to remove points, once they’ve been clicked (sort of like doing it in-game!) Kind of irritating to go through a potential build but if I want to switch out points here & there, I have to start from scratch again?! Just a QOL request, in case anyone at Gearbox wants another task to attend to!

Official Skill planner –

This, unofficial one is nice but I’m not sure it’s being maintained?

There’s a way to remove points, albeit not very user friendly when you near the end of a build and decide some early points should’ve gone elsewhere - undo and redo arrows at the bottom.
