I think it would be great if size of soft tabs and normal tabs would be two separate settings as in some other editors (IIRC they are called “indent size” and “tab size” respectively).
For example, I usually use 2-space indentation but I also occasionally edit files that use tabs for indentation. I’ld like to use the auto-detect-indentation package to detect when I’m in the second situation and swtich to tabs automatically. The problem is that I want tabs to be 4 characters, not 2.
What do you think?
