The replay speed variation and delayed captureare both great but are both a little fiddly/inconsistent with the slider bar. It works brilliantly for fine tuning but some speed presets could work well. Steps to each side maybe - half/quarter/eighth/16th speed and to 8x/4x/2x/ speed etc or individual speed buttons, or R click options. Similarly it could help in setting up a delay to skip to 2 secs/4 secs/8/15/30/60/120 delay as presets
Likewise in playback and in delay a shortcut to skip back and replay from 5 secs ago (?time set in preferences)would be a neat way to get that shot again with one click
Thoughts?
