I'm still curious where to find an explanation / setting option for those little exclude signs in the top right corner of some albums.
Say you have applied an image effect on the
Settings > Effects tab, like a watermark. But you want to exclude a folder from that watermarking, so you right-click on the folder and choose
Effects and un-check
Text. Now, you'll see that little icon.
There is a bug in there, however. If you decide to get rid of the watermark for the whole album, and remove it on the
Settings > Effects tab, those little "excluded" icons don't go away. They're not doing any harm, but it's a bit of core sloppiness.
I reported this many months ago, but never got an answer about it.
