I was wondering if a sliding drawer could be used. It would show the open library’s folders, and allow drop of files to a specific folder, sort of a supper drop pad that would be out of the way until needed. That way I can minimize Eagle Filer and use the whole screen and click on icon on the wight side of the window and i would show up. Just doing this for the drop pad would be real nice to.
Have you considered using Dock Exposé for this? You can drag onto EagleFiler’s Dock icon, then onto the desired folder in the minimized window.
