Would it be possible to make filters for the gcode rendering for milling mode

Would it be possible to make filters for the gcode rendering for milling mode to show certain things? (1) lowest Z for any X,Y position (2) movements faster than a certain speed (3) rapids (4) non-rapids (5) X,Y positions with only 1 Z cut

(2) there are only 2 feeds, g0 and g1. You tell it what g1 feed to use on the operation setup

Oops. I forgot plunging. There are 3 feeds.
