We have raised the priority of this work item, and it is currently being worked on. We don’t have any dates to share at this point, but will update when we have new status. Thank you!
We are now preparing for the roll out of Tasks in Teams which will integrate additional features integrating To-Do and Planner. This includes additional list views that also extend to tabs in teams. Further announcements about additional integration in our overall Tasks coherence effort will follow.
You can follow the rollout via our Roadmap item: https://www.microsoft.com/microsoft-365/roadmap?searchterms=57213. To see a preview of the experience, please visit https://youtu.be/rTATVGroEsQ.

The ability to add custom emojis and custom reactions is still under review, and we will share an update as soon as one is available.
Removing the Conversation Tab is being reviewed by the feature team.
