Select All Layers cursor no longer working

3.4 (3401)

compatible layers, selecting nodes in one layer no longer makes it selected in another

Oh wait, I misunderstood how this tool works. However, it still doesn’t work as it should according to this page: Editing Multiple Masters — Glyphs Handbook
I can not edit multiple layers at the same time even if they’re visible

When you switch to the Select All tool, sometimes you need to click the draw tool and then go back to the select tool (I really need to fix that).
