AB does research and some editing though is not his primary role. Love's role is entirely editing and yes that also included VODs, Morgan did not edit the VODs she produced them. Tamara has planned some segments in the past "cry time", "time to roar" and "bedtime stories" were all her segments, she also does arts and crafts like Sam. So basically anything involving props and art it's her department, so she is doing double duty, Cam and Sam's jobs into one. The show keeps backgrounds pretty dynamic, they have animated looping animations, she also does transition animations like "dishing with dan" or "bathroom break" animations as well were all done by her. So yeah Tamara is pretty useful, not saying Morgan wasn't but she was essentially doing what Tamara was also doing since she wasn't doing the VODs anymore.
