I’m already at work on 0.8.1 and it’s going pretty well. I’m rewriting most of the core code (again) since 0.8.0 has some nasty memory allocation bugs and code organizing isn’t very good. 0.8.1 will strip most of the bugs that 0.8.0 introduced, making it quite usable. Should be coming in a few days or so, depending on my spare time. The “Lock zoom” option will probably be available in 0.8.1, as well as a few minor improvements. Also, the bug not displaying “Fit to window” correctly. The scope for this new release remains stability though, not features.
