In the new “lock” mode the mouse is useless. The humongous tooltip asks me to press [?] to interact, which sadly is not the question mark key (I tried). As I see it, even if it worked it’s going to require an extra key or extra click while before it was just simply clicking-dragging. I don’t see how “lock” mode is an improvement for us PC users.
In legacy mode nothing shows up while it did before.
