Being a theory instructor I am really looking forward to the day when this will be incorporated in Dorico. That and a quick graphic copy like alt+G in Sibelius. Ok, I also want fully supported figured bass.
Roman Numerals: One thing that bothers me with a lot of roman numeral fonts and workarounds is the use of serifs simply because I find it is problematic as a teaching tool for students that will be asked to do analysis by hand. I currently use a modified version of the font shpfltnat as it incorporates beams for major chords. I also do a couple of other less common things so I just would like to request that the roman numeral analysis system, whenever it is put into place (I hope soon!), will have the same flexibility that chord symbols with the editor have.
