Version: (using KDE Devel) Installed from: Compiled sources OS: Linux Plugin saves settings from previous usage. IMO this is nonsense because each photo is different and corrections will be different. Two possible solutions: 1. Better: don't save settings at all. 2. At least give button for resetting *all* channels. At the moment you can reset only current channel.
Sorry, 2. is applied as Default button restores NULL state. Still think that saving settings isn't good thing.
I am closing it. Really don't like this behavior but with easy reset of settings this is not so tragic. Also for many plugins saving of settings have sense. Splitting them for those who save settings and for those who do not may confuse user more than enforced pressing of 'Default' button.
