This addon is what I wanted. Thanks to the dev. But this addon isn't perfect yet. First, the color of the interface being added does not match the background. Second, the placement of the interface makes the layout ugly. I would like an option to hide the index number on all screens. This review was generated by machine translation. I'm sorry if there is a part where the intention is difficult to convey.
In the new version 2.0 there is now the option ✔️ "Only show on hover or selection" but in version 1.9 there was already the similar option ✔️ "Transparent background color".
