Shulker obstruction is now checked the same way regular chest obstruction is checked, preventing blocked shulkers from being opened.

Kindly noticed and implemented by Github user @WMGameLive

Clickthrough now works with signs as well!

And we (I) fixed a bug where you could still open chests even though they were obstructed. You can't anymore

That's about it, if I included any other bugs let me know, and if you like it I always appreciate if you'd also rate it
