Is it possible to have the mod tooltips load after Crafttweaker, so that any tooltips added via scripting can display above the mod name itself?

No idea why I never got notified about this at the time.

It may be too late, but anyway...

The tooltip functionality was very primitive in 1.12, we were probably using lowest because some people would want to remove everything, including tooltips added in low.

If it is worth anything, it is much better now in 1.16 so this wouldn't be an issue on new versions.

Thanks for the info Jared!

Any comment on this @mezz?

ModNameTooltip already subscribes to the tooltip even with LOW priority so that other mods can put their information first:

Crafttweaker may also be using LOW priority, I'm not sure.
@jaredlll08 do you know more about this issue?
