There is only one thing that still works wrong: when an excluded image is overwritten, it is no longer excluded.
I understand, but that seems harder to implement.
I see two use cases for this:
- An image is not nice enough to be included, so it can be overwritten by a new version that will be included: the current behavior is not a problem.
- An image is only there as a header image without appearing in the album (e.g. with the Tiger skin); overwriting it with a new version can happen from time to time, and the user probably pay attention to keep this image hidden, so he will hide the image after replacing it. This should be very rare.
So, IMHO, it is acceptable if the current behavior persists in the next version.
I was hoping that the Undo button tooltip would display a list of all the actions that can be undone, one by one, a bit like the tooltip displayed on the pencil of an edited image in the Explorer view:
Image tools applied (Straighten Filer, Grayscale Filter).
But a tooltip displaying the action that will be performed when you click Undo is already not so bad

Not that it's hard to display all applied filters in the tool-tips, but it would be confusing as only the last applied tool will be undone. If you undo one too much, just hit redo again.
That's right, and it's better not to add confusing stuff
