Remove all played tracks from tag list option

Hi there,

My suggestion for a feature, is to add an option to remove all played tracks from tag list. 

Currently the max total of tracks you can have in tag list is 100 tracks. During long gigs, i tend to reach the limit, and i have to manually go in and remove already played tracks from my tag list, to make room for new track to be added. It would be awesome to have an option in the settings for taglist, to just remove all already played tracks.

I hope the feature can be added at some point! 

Cheers.
