I already have HWYLA installed (a WAILA replacement) and I have no clue what the blue identifier is at the top left. Anyone know what mod it is from??? Thanks!
I think that's "The One Probe", further description on the CurseForge page: https://minecraft.curseforge.com/projects/the-one-probe
I can state from personal experience that the beginning of the description is out of date - default configuration doesn't require the probe for showing the tooltip, but I'm fairly sure it can be configured that way.
THANK YOU SO MUCH!!!
