I have been wanting a simple check list mod like this for a long time. Thanks for making it. I have some strange behaviors though.

When the clipboard is attached to a block and I right click it to open the GUI then hit esc to close it, I automatically jump in the air and get stuck sprinting. Really strange. I have a large mod pack so interactions could be causing it but it definitely happens.

Can you reproduce? Need a list of my mods?

Another couple of things. Wrenches can rotate the clipboard to 'air' sides of the block, really which would be the air block in front of the one it is hanging on. Also between game sessions the list may empty. I can open separate issues and edit this one if you want.

What version of Minecraft/Forge/Clipboard are you using? Which wrench are you using to rotate the Clipboard?

Minecraft 1.10.2
Forge 12.18.3.2185
Clipboard 1.10.2.1.1.1

Morph-o-tool but I think it is selecting the Yeta wrench.

I figured out which wrench was rotating in space and it is not just your mod (so not your issue) It is the Scrench from OpenComputers.
