Suggestion: Filter menu option

I have 10 or so relatively complex filters I use all the time from the history list but soon enough another 20 or 30 other items have accumulated in the history that I must then manually delete each one in order to preserve the 10 I want to keep.

Pin to history
Remove from history
Remove all from history...

So now I can use ""Remove all from history" without losing my favourites!

Nice idea.

For the time being you could create a plain text file where you store those filter expressions and then copy&paste them back into mp3tag.

THis has also the advantage that you could add comments to clarify the purpose of a particular filter as the filter syntax is sometimes not very self-explanatory.
