Arduino IDE is not the best choice

[pert]

Discussion specific to @jimLee's specific problem with configuring Arduino IDE 2.x to use tabs, and to size them to 3 spaces will be done in the dedicated topic for that subject:

Setting tabs for code formatting

So, I like to use tabs for code formatting. I searched and found the hidden. cmd-shift-p thing that can be used to allow this. I was able to even set 3 spaces for tabs as I prefer. But then, the next time I open the file, it has switched back to the nonsense it used before. How do I get it to save my 3 space for tab setting? Thanks! -jim lee
