First of all a solid thanks for great editor.
I work on many languages at same time - for work & for hobby. One thing i have to keep changing each time is tab settings. e.g.
When editing XML, i use "TAB=width:2, convert tabs to spaces.
When editing makefiles, i use "TAB=width:8, keep tab"
Would be useful, if the tab settings was part of the language preferences.
Can this be achieved via a macro?
