@gibelium each hyperlink leads to a corresponding Github issue that has been filed. Please take a look add more context to them if it helps. 
It seems they are all still open issues.
Couple quick thoughts:
- Circles app has not gotten any love for a long time. See this detailed review I wrote in 2018.
- Comments have not gotten any love. These are decent features requests, but focus has clearly been on talk app for guests and communication.
