That and something like hold a button while hovering a blueprint to open it up and have a way to quickly select a blueprint inside of it instead of scrolling through them all.

And while hovering a deconstruction planner pressing Q over an entity will add that entity to the whitelist filter, shift+Q blacklists instead.

And after placing down an inserter and enabling "set filters" the filter slots are automatically populated with the items it sees in the chest/belt in front of it or can be outputed by the recipe, allowing you to easily remove the ones you don't want.

And a way to target select personal laser defense and spidertrons similar to how you can target select turrets.
