What add on is this please

[Mugetsu]

Can someone please tell me what add on this is I can't figure it out and idk what those sums are I assume there some kind of resource in the game, I installed some adding cause they seemed useful but idk what add on this is and since I don't know what it is I can't go into the settings and move it around I don't want to get rid of it because I apparently installed it for a reason.

One way to find out is to disable half of your addons, and see if it's gone.
Disable the other half if it's still there and go on with the half of it, and so on.

You can use the addon "Addon Selector" to save packs so it's easier to reenable the halfs.
Mass marking/demarking can be done with SHIFT click there.

Another trick:
Move the mouse cursor above the control on the screen an type in chat:

/script d(moc():GetName())

It should output the name to the chat then.
The start of the name often is the addon name then.
btw GuiRoot is the base control of the UI so that's no addon.
