i use diffuse for about half a year and i like it. There are some little things i would like to be able in Diffuse.
Its possible to exclude whitespace. Can you make a filter for ignoring remarks as well ? There are severall remarks possible of course, like REM ; // and <--. A chioce for one off these would be perfect and makes it possible to concentrate on my z80 asm files instead off the remarks i add myself.
