User story: I had this idea from my practical personal experience. I’m in multiple groups and sometimes I want to navigate between the activities I’m signed up in different groups, so I need to change group first. I think it makes sense to move the upcoming activities to the top bar, put some icon there like a calendar or something…
I also never like the space it takes on the main wall and I think this could resonate with other people’s experience. Although it’s a good reminder, it’s annoying to always see it and have to scroll down to get to the wall
I liked this one in discord, that’s for viewing threads, but interesting I think as it’s more than just a simple menu, it has extra stuff for filtering/searching
or another idea, could be it opens dialog in the middle of the page for navigating upcoming things, e.g. like (with or without a search, we don’t currently have search in the backend… so yeah…):
One thing that would be nice to have… If we go for the icon somewhere at the topbar (need to consider mobile too, so it’s not too crowded), it would be nice with a calendar icon
and add a little counter with the number of upcoming activities. It can also be color-coded, with if there’s an activity within 24 hours, or otherwise
if there’s an activity within 24 hours, or 
otherwise
