Numbers for item stacks in the hotbar are not disappearing it seems.

Thank you for this great mod! :-)

Edit: Sorry, my bad. After further testing, this seems to be an incompatibility with "Immediately Fast"!

I am getting reports of similar behavior with Caxton.

Edit: I can’t reproduce this issue without ImmediatelyFast.

As of ImmediatelyFast 1.1.8, it appears to work fine in both move and fade mode, as they have disabled item batching by default.

See RaphiMC/ImmediatelyFast#16 for reference.
