It is VERY tedious to organize Apple Photos on the Mac with just one window. I know there are ways to SEE two windows at once, but I need to be able to drag/drop from one Photos window to the other in order to much more easily organize.
Until Apple finally solves this (crazy they haven't already, as so obvious), I need to find a 3rd-party app that would allow me to do this. Does one exist.

While it does not address your issue directly, Houdah Software has its (currently in Beta) Photos Workbench, while not directly addressing this issue does make it easier to organize and does allow to compare two images. It does this by working with Photos, not replacing it.
PowerPhotos can help a bit. It can show you a second window for your Photos Library and allows you to drag and drop photos, albums folders between Photos Libraries.
While browsing one of your Photos Libraries in PowerPhotos 2 you can drag items to albums or reveal the currently selected item in Photos. Bur even PowerPhotos does not let you drag items from the PowerPhotos window to the Photos Window. http://www.fatcatsoftware.com/powerphotos
Oddly enough, I can't think of such an app. It's not possible in either version of Lightroom, CaptureOne, Mylio. It might be possible in On1 Photo Raw.
Two Apple Photos Windows open at the same time?
