Allow switching between shards in the profiler and/or have a combined view
Since the profiler tabs are shard specific, it would radically improve the usability to:
a) Combine the profiler events to truly have a cluster level view so you don’t need to worry about shard specific views
b) Add a drop-down to the top of the page near the title that has the various shards listed in it, selecting a different shard brings you back to the same tab, but now with the changed view.
c) Consider tweaking the URL so that rather than using a SHA in the URL, you use the shard name, making it easy to manipulate the URL to change the shard view

The Atlas Query Profiler now consolidates all slow queries in a single view. You can filter down to see slow operations for specific shards/nodes via the filter selections
