Fingering in Fretboard Diagrams

Most guitar fretboard diagrams I've seen have not included fingering numbers. Notwithstanding, perusing some published guides results in seeing some fretboard diagrams using numerals (in white text) within the black dot positions of frets corresponding to finger numbers (1=index, 4=pinky; my guess would be that 0=thumb). This might come in handy for future implementation. Maybe some options (a style?) as to what the font and size would be regarding the fingering of the chord diagram should be available to the user. With this it follows a resizing of the diagram for easier reading ought to be considered; possibly a "maintain aspect ratio" resizing on chord diagrams could be implemented to customize how they will be used on a given notation sheet.

Hope this gets considered for Musescore's development.
