I don't know whether this is feasible with crunchyroll's APIs, but ideally it would be nice to be able to link my kitsu and crunchyroll accounts so that when I finish an episode on crunchyroll it updates my library (or suggests an update), and when I add a show to my "Currently Watching" list on kitsu it gets added to my Crunchyroll queue if it is available on Crunchyroll. This may be impossible but we can only dream.
