More Guitar symbols?

There may be some symbols that developers may consider adding to the palette. See Acoustic Guitar Notation Guide .

An extensible slide symbol as shown further down the page would be useful, both before and after the note, down and up. This could be used to annotate non-specific slides to and away from the note as well as slides between specific notes.

And I think electric guitarists may need the various kinds of bend symbols, also shown on the same page..

There is another guitar symbol chart at: Guitar notation legend , which also has some more standard symbols
