In the Photo Info Pane on the right, add '+' and '-' Buttos to add to or remove from albums

When I'm in the overview in desktop and web app, I can mark one or more photos and hit the + button to add them to an album.

When I open a picture and click the "( i )" Button, i scroll down and see the albums this photo is in.
I miss a '+' button at the end of this list of albums to add the photo to another album.

While I'm writing this, I imagine a '-' button behind every album my photo is already in would also be helpful here, so I can remove the photo from one album with '-' and add it to another by clicking '+' and selecting from a list of Albums.

Just a thought: Maybe instead of separate '+' and '-' Buttons which could lead to unnecessary clutter, one could also use the 'folder' Icon on the left side to open a list of albums.

Ideally with checkmarks allowing put the photo to (or remove it from) more than one album
