On the panel that shows details about an item (like liquid amount in a pipe), I'd like to add GUI elements/info for some of my custom prototypes.

I cannot find a play to really start on that, though I see LuaGuiElement, and I could probably iterate down the GUI tree to find the parent I want, I'd rather not do anomalous functionality and outright abuse the system. Are there any examples on how I might do that or places I can start to tinker with to figure that out?

Thanks, guys!

Any vanilla GUI can't be changed with mods. I am waiting for 0.17

Shoot!
So my best option would be to make my own GUI element from scratch that "looks"/mimicks the on hover inspector to add my own elements.

Is it possible to show/hide a GUI element on the player hovering over a specific prototype?

You'll still be limited to gui.left/top/center though. And for left/right you don't really know what other mods have already added stuff there so the position will be somewhat random,

It might be worth a try to make a modding request for a "selected tooltip" gui position. i.e gui.tooltip. that's displayed above/below the normal tooltip.
