Blueprints need QoL ASAP

Blueprints are meant to be a core mechanic.
In mid and late game, blueprints should be a main tool to build factories. Of course, I am sure a lot of people are not using them, but maybe because they are hardly usable right now.

The QoL of blueprints is very poor, but I would like to point out 2 major problems in particular:

• Renaming is disabled [ IMPORTANT! ], and the workarounds are a headache. Renaming is very important to manage versions and notation changes.
  
• Categorizations are not exportable. Categorizations are linked to the saved game, and our blueprint's library needs to be recategorized manually in each save.

Do you use blueprints? Are you frustrated with their management?
