Currently the workflow requires a download from the source (PW or project documents) and an upload to plan set. That leaves up to 3 copies of the same file.
As you can move PDF's in the PlanSet around by draggin them it would be nice to delete a file as easy. Eiether an option to select and drag to a trash can or a red "x" rather moving all the way across the screen to the 3 dots to find the delete.
