User Interface:
The list of layers moves up and down if you have a layer selected or not. Its annoying when editing a mask as the layer selection is empty after you switch to mask mode, and when you click the back button. I’ve also had problems with layers getting moved in the stack when I click on them because photoflow is mistaking the UI movement for a drag and drop operation.
Raw Developer:
The advanced settings (white level etc.) don’t seem to do anything. Mostly this isn’t an issue, but for some raw files (e.g. Morning mist in salted meadows (Arcachon)), the white clipping level is slightly wrong and the sun comes out magenta.
Scale and Rotate:
The ‘height’ scale doesn’t seem to do anything. Again, not a problem usually (different X and Y scales is unusual). I noticed it because I tried to load a Nikon D1X raw file from a recent Play Raw (can’t find the link, sorry) and it comes out stretched horizontally.
I am finding that you can’t edit the rotation points on the image once you have set them (unless you move the angle slider a bit - that seems to fix it).
Crashes:
I don’t have a reproducable test case, but I seem to be getting more crashes when turning layers off recently. It seems to be the histogram that fails (usually by accessing a nil pointer).
Crop:
The new UI seems nicer than the old one. It seems easier to see where the edges of the crop are than with the previous one. I don’t think you need to change the mouse cursor - having the handles on the crop area appear and disappear as you mouse over them is enough feedback for me.
