I am a happy user of xnview pocket for some time now. For your information: I am using an x51v, so VGA, with WM 6.1. I have done some transformations on hundreds of images at a time, and sure it takes its time, but it completed successfully without crashing. I found that especially impressive.
I decided to join the forum to take the opportunity to suggest some new features. I hope they are not duplicates, I did search for them. I will do the suggestions in separate posts.
So the first one: I need to keep the built-in picture viewer mainly to change the todaybackground. Is that something you could add to xnview?
