Just a few suggestions that would make my life easier...
1. more flexible DAR in configuration of mp4, mkv, etc. , e.g. like PAR in output1 tab not just a few ratios
2. when playing in main screen I have to move position, play to move about.
Can this be done automatically? e.g. I'm playing a video and I want to seek 10 minutes ahead and carry on playing by just clicking 10 minutes ahead.
3. autocrop in the crop filter needs to slightly more agressive, usually it is 2 pixels short of removing black edges.
4. can the filter windows that show video have a maximise button? e.g. the crop window.
5. a delogo filter that can use a mask would be good.
Otherwise it's perfect...
