From the release notes:


Using Effects, add a text watermark. Using the context menu, exclude the effect for one folder. Now go back to Effects, and remove the text watermark entirely. The folder still shows the icon that indicates that there is an excluded effect.

And changes done this way require a Force Remake - the core doesn't seem to know what images it needs to reprocess, particularly after the removal of an effect from one folder.

There seem to be some other inconsistencies, which another confused old man, who shall remain nameless, is currently exploring.

The effects under settings are typically only applied to slide images.

There are some historical reasons as to how effects / image tools / filters have evolved over the years. If we remade everything, we'd keep a more intuitive model. Now it's a hybrid.

Even worse is that all of the images in that excluded folder show the excluded effects icon, all images in included folders don't show the icon after the effect have been removed.
