Wow! This thread’s way more popular than the original.
The 2 space 3 space thing seems to be inherited from the 1.x version. I could set that one at 3 spaces. But auto format ignored that setting and just blindly reset everything back to 2. It felt like it was trying to teach me a lesson. You may ask for the cookie, but you still don’t get one! Kinda’ thing.
Having a Mac I do about 90% of my editing in BBEdit, and only the .ino & it’s sketch sibings “live” in the IDE. I’m actually starting to like the 2.x IDE. I don’t completely trust it yet. But I’m getting used to it. I feel it’s a step backwards on the 2 space 3 space thing in that the 1.x at least saved my setting over time. This one just tosses them when the session is done.
