For chest and shulker, allow skipping to the vanilla UI by holding left click when you right click.

This might not be the best shortcut, especially for creative-mode users. Need to think on a better solution here.

Thinking of doing SHIFT+Right click again, and bypassing vanilla behavior for it.

Re-opening. The mixin for the server-side's gamemode needs to also happen client side to prevent short de-syncs and more severe ones (like with the Shulker rendering closed with the UI open)
