My HTML files are configured to use syntax indent, +4.
My ruler is configured to show syntax indent markings.
Just confirmed it works in C/C++ and Slick-C files -- but in HTML, Lua, and Txt files there are no markings on the ruler.
I suppose maybe the ruler type could be configurable on a per-language basis, but I wish that the syntax indent ruler could show normal tab stops when syntax indenting is not applicable (but in HTML and Lua syntax indenting does apply, according to the Options dialog, yet the ruler doesn't show markings).
Confused, or maybe just bleary-eyed...
