Portrait touch overlay

Hi, I need help creating a touch screen overlay for portrait mode. Is there any overlays that look like this one:

many of the overlays have a portrait orientation similar to what you’ve shown. Tap on the button that looks like a three-quarter-circle arrow.

I’m trying to make this overlay right now but it’s too hard to resize and place elements by editing numerals in cfg file. Maybe there is option to show button hitboxes and other information in retroarch?

That would be really helpful for creating/modifying touch gamepads!
