[quote=paultaylor]You can filter rows using the TagBrowser.
You can fiter using Search button, this searches the artist, genre, album and title fields.
Task are only applied to all visible rows if nothing selected in row header so you can close selected songs by selecting their row header and selecting close leaving you with just the ones you want to work on. You can apply a task on certain songs by selecting their row header and then selecting a task
But you cant temporarily mark songs in the way you request. Got me thinking though that if I extended Search to search on the Custom fields (Custom 1 - Custom 5) then you use Set Value to enter a value and then search to only show those records, is that worth me doing ?

If the custon fields is easy to do and not to much trouble that would work for what I want to do.
I will have to look over your other suggestions and try them out.
Thanks
