Describe the bug

I want to hide all Bits, but I can't select them all.

If I do Select All, that includes the Chisels themselves.
I have to Select All then Hide Selected, then click a Chisel, unhide it, click the second chisel, unhide that, and so on.

Environment (please complete the following information with the version):

• Minecraft: 1.16.5
• Mod Loader: Forge

You should be able to drag and select, like how you select multiple items on the desktop

Ah, I can. I tried to control-click and shift-click only.

I can't deselect only certain items while keeping others selected, however.

This should be implemented now.
