This makes sense! Can we add it to the right side of that bar? This is a more common placing of this feature

@ssidharth010 only issue I see is that the left/right arrows don't seem to do anything. What is the intended behavior? #5203

[christian-byrne]

Actually, it seems the arrows were not added in this PR and were already broken. #5203

Test failures are unrelated to this PR -- still updating new CI workflows to work on a fork cc @snomiao

LGTM, thank you for adding this.
