Correct. Lawyers load their Word instances up with many add-ins specific to their practice. Microsoft Word add-ins are the entire product surface for many legal tech companies.

It's somewhat analogous to how coders use add-ins in their IDE but if only one IDE could run them.

Not a lawyer, but for the last 20+ years I've dragged around (or recreated) a normal.dot file that has all the styles I use with the keybindings I like.

The productivity boost you get from having a consistent environment is insane. You never need to care about the ribbon, your documents look good, and your mouse/keyboard ergonomics are wonderful with a good normal.dot.

It's like people who have their vimrc or emacs config down to a fine art.

Oh, that makes tons of sense. Yeah, that would basically mean a switch to anything would never happen, I definitely see that. Thank you!
