Those are some of mine:
1. Vertical IPD alignment fixes unwatchable DDF, StockingsVR, Reality pussy videos.
2. Horizontal IPD alignment helps to get centre or edges clear depending on where the action goes. It would be probably a good idea to save horizontal IPD for video timecode, not one value for the whole video. That way I could adjust the whole video for myself
3. Saturation makes big deal for most SexBabesVR videos.
4. Height adjustment fixes many scenes, but only for specific part of the video. Some default height feels really creepy once on very unusual distance from the floor. Also would be great to have timecode specific settings in players.
