Ability to skip tasks while marking them

It would be really cool if you could choose which tasks you want to mark. If you have multiple alts, I just find it really weird to mark my own tasks because I can’t skip them in order to get to other people’s task. Sometimes you also aren’t in the mood or don’t have the motivation to mark tasks for certain lessons and by the time you have forcefully worked through them, you aren’t motivated for the ones you actually want to grade anymore.

Additionally, it would be good if Teachers and their helpers would earn points/merit/depending on the site when they do their job too.
