On my todo is to create a PR to 52 for these. 926 is to create availability lists to show when you want to accept booking requests and 927 is just a public busy time that I create when users create gift wrapped 393 so that the booking can still see the user as busy without knowing why.
I will definitely send a PR when I have them working well. I slid away from the android side for a few days and started putting some focus on another project but will definitely get it over.
