I already thought about making many* of the special context menu entries in foo_dbsearch regular context menu commands. This way you will be able to remove them, if you don't want them. I also thought about putting those actions into a separate plugin. If there's a request for this, I'll probably release this plugin a little sooner.

*: Currently, the actions that send, add, or insert entries (in)to the playlist or on my list, as well as "Remove from database".
