Ability to configure Wacom ExpressKey Remote not discoverable
The screenshot below allows an ExpressKey Remote (EKR) to be configured; is it immediately obvious how? In order to configure an EKR in GNOME, the user is expected to notice that a tiny triangle has suddenly appeared next to unrelated text in the "Map Buttons" overlay and then further assume that the triangle is clickable. The visual difference is so minor and the UI so subtle that I feel it is practically non-discoverable.
