This is more a design question, but could also be a normal issue.
I like the feature to open the ender chest in inventory.
In normal vanilla minecraft, you need a silk touch pickaxe to break the ender chest to get it back into your inventory after usage.
This mod bypasses this necessity.
My question is, if there could be a check added, if the user has a silk touch pick? Maybe as optional config.

I believe this is a bit out of scope. There is now a config option to disable the ability to quickly open the ender chest
