Please add some more in-depth controls for rendering image sequences. These are the options I would love to see in the output module (I know some of them exist already):
1. start frame (timeline)
2. end frame (timeline)
3. increment (timeline)
4. start frame (output file)
5. increment (output file)
6. skip existing frames
This would give you so much more flexibility than currently. Maya does this very well.
