The documentation says that flipping horizontal or vertical only affects the "active layer." Yet I have tried a dozen times, even hiding the other inactive layers.
With only one layer selected, a flip horizontal action still flips ALL the layers. Is this a bug, or is there something I am missing? I noticed someone wrote a plug in, but a) I haven't installed any yet and didn't want to bother just now, and 2) I have a hard time believing it doesn't work as documented, since that's how every other paint program I've ever used, does. Thanks in advance.
