Option to hide all entities or certain entity domains in Developer Tools -> States

I have a ton of entities (over 4000), so loading the Developer Tools → States page takes some time and is fairly unresponsive. Turning off the attributes checkmark does help, but having the option to not load all entities would make it significantly faster. I only use this page to find the state and attributes of specific devices that I can just type into the entity dropdown, so displaying the full list is just a waste of resources.

Probably wise to vote for your own Feature Request

This is getting out of control. Please give us a filter to hide unavailable devices:
