You know what would be awesome? If I could scroll on my board but all of the filters/search options stayed with me on a sticky header and I did not have to scroll up to the top of the page to re-filter or search. Would save a lot of annoying scrolling back and forth just to use a filter.
+1 would be awesome. To add to this also include the board title / activities just above the filter/search. So basically stick everything up to the horizontal line
A similar feature request was posted in August 2019. No action to date by the Monday devs.
Feel free to add your vote to that too.
+1 Simple change that would make it so much easier to view large boards / groups
