[Enhancement] Track filters, automatic track colours based on filters

I track and store a lot of my outdoor activities, and Maps currently does find and show them well. However, while sorting by date is nice, sometimes I want to look at an older exercise I did a few months ago, but cannot recall the exact date. It would be nice to somehow be able to filter tracks by e.g. average speed, or total distance. I imagine it could look something like

when a filter is applied, and filters could be selected via the three-dot menu.

Actually, one thing that I think would be nice/fun would also be automatic colour selection of tracks based on such filters. For instance, I have a python script that runs in a terminal, but allocates an "exercise" to each track based on a combination of speed and distance. I would really like to be able to set up and use such filters to automatically assign specific colours to each track.

Review the existing track sorting and the three-dot menu entry points, then determine how track data exposes average speed and total distance. Done would include user-configurable filters and automatic track colours based on those filters; the issue names no files or tests.
