Nice ! I'll have to test the following :

• resizing the display
• removing a hand
• addding a hand (might be tricky as there's issue with the add hand command I think)

Removing hand makes slots shift, I didn't consider this, the second solution (https://github.com/RE-SS3D/SS3D/issues/1365#issuecomment-1849520811) might be the appropriate one.

@jckling okay thanks for testing it out !
