Tooltip for entities

Right now see, f.e. in Device screen in Settings, in tooltip just the same entity friendly name.
Woulde be nice to define tooptip text for each & every entity to show additional info for user.

Just for example - hovering over entity tooltip appears with same name, which is actually useless IMHO

Would be nice to define some comment/details of entity to be shown as tooltip in browser.

Do you have a picture of this, I have no idea where this is.

Added screenshot to first post.

OK, then this is a frontend request I believe. That is in a Home Assistant window or in the ESPHome Compiler add-on screen?
I ask because if frontend, the [FR]'s go somewhere else…
