Thanks for the feedback Loz! Unfortunately there is no standard way to save files in the same location as the DAW project file. Some DAW's like Reaper provide an API which can be utilized to incorporate this kind of functionality but there is not a consistent implementation that can be made to work across all DAW's. Utilizing the Reaper API as Pipeline has shown is definitely on the backlog for the plugin but because it only benefits Reaper users, it is not something that is being given priority at this moment. What I can say is that the plugin is designed to remember which files were dragged from it so if you have dragged certain files from the plugin to your DAW, then it will make sure not to delete those files when it clears plugin directories. I hope this helps!
