Better "sort" which channels are seen

As a person with severe ADHD object permanence is very limited. So "out of sight out of mind" can be quite literally for me. So to counter that it would be good to manually choose which channels are seen when the category is closed. Some kind of pinned channels would be good and having an option for if channels should be seen if they got new messages when the category is closed. I hope that helps and also I hope these features get integrated soon in that or a similar way as getting overwhelmed is also a big trouble for much neurodivergent folks (People that have ADHD, Autism and other chronic mental illnesses or disorders)
