Feature Request: Fretboard improvements for better learning

[nicolagranata]

Request: automatic note text color for "Note color" with "Display Note Text" ON:

• if i use "yellow" for note color for more contrast on dark fretboard without "Display Note color", when i enable "Display Note Text", on white background, yellow is unreadable;
• E.g. use Note Color as "background color" of note and if this color perceptive luminance >=128 (in 255 range), note text color is black/dark (custom color), else is white/light (custom color): -- Note Color -> Yellow / Note Text -> Black; -- Note Color -> Blue / Note Text -> White.

Request: The rectangular shape with "Display Note Text" ON is ugly: is possible to show note inside a circle?

Request: show bending on fretboard (using same symbols as tabs) or move up the shape of note with arrows tath show the range of bend (more bend = more slide up arrow), and animated change color (custom color / glow color / light color) for note with bending up (change color) and release (return to original color)

Request: Show/Hide frets number with general color customization and presets (top/bottom):

• all numbers;
• only standard ref numbers (eg, 3/5/7/9/12 ... etc etc) ,
• all numbers with reference numbers highlighted (and highlighted color customization)
• custom numbers ( eg. 5/9/12)
• Position: top, bottom, inside fretboard between 3 and 4 string, or inside fret markers

Request: Misc.

• option to show 12/21/22/24 frets (or custom number) ;
• option to chose size of note circle on fretboard;
• option to automatic / custom vertical fretboard resize to prevent overlapping of notes over strings in same fret or for more readability;
• option to horizontal resize fretboard inside window (with window maximized on 34" display, fretboard is not user friendly);
• option to improve frets interval sizing to reduce the flat effect (all frets with same size) on large display;
• options to move fretboard up /down on UI or left/right (with 90 degress rotation);
