Binnie uses "Hold Tab for tooltips", which forces the user to invoke inane tricke to activate the feature, when Tab key is already used for other actions. For example, to open Inventory.

Can this be changed to a more sane hotkey? F.e. "Crouch" key like other mods using.

I made some changes today so that basic help is shown on empty slots.
Advanced help is shown when holding the Tab key, which is now configurable in the controls. It is also enabled when you have advanced tooltips on.

TTTT, I consider it a bug.

I think tab was chosen because shift is used to show extra information on the items in the slots already.
On the latest version we should make it a configurable hotkey using the GUI context.

Yes, I don't think this is a bug. Any other key will conflict with the same or something else. There should be a setting, but for MC1.11.2 (1.12), because for MC1.7.10 it's a feature.

For MC 1.11.2 or 1.7.10?
We don't add new features for 1.7.10 anymore. Only bugfixes and localization.

I think tab was chosen because shift is used to show extra information on the items in the slots already.

I'm failing to see, how "Information on items in the slot" conflicts with "information about UI elements".

Shouldn't that appear on an empty slot only?…

Unfortunately, due to the fact that Binnie wrote his custom GUI, any improvements to it can incur a lot of edits in other places. This improvement can be made for 1.11.2 (1.12).

Because if you need shift for additional info of bees...

But you can see this...

Thanks for clarification.
