Add-ons you can't live without?

Let's make a list of our favorite add-ons! For me, I always enable these by default:

• Images as Planes
• LoopTools
• Copy Attributes Menu

Then I go out and get my favorite 3rd party add-ons (note, some of these are paid, some are free):

• AutoRig Pro
• fSpy
• Send to Unreal

I'm sure there are others but this list is off the top of my head. What do you all use?
