I'll add : A way to use the pose maker from the Beauty menue for Screens

These are great suggestions.  A toggle to turn off player mounts would also be a nice feature to have in screenshot mode as well. It would be perfect for when trying to take scenic/landscape shots in busy places; like the cities or event areas with tons of horses parked around!

Great ideas!

I think an easy to implement idea could be when the player paused the screenshot mode, they could press something like left / right arrows to change the animation frame by 1. Of course, a proper key combo would be needed because the arrow keys are already bound but it would make such an improvement to just move the keyframe animations one frame at a time instead of having to keep retrying over and over until you get the perfect pose. Perhaps you could even click on other characters and pose them correctly in this mode since it's really hard to get two or more character animations to be in perfect sync.
