"Reveal In Sequence" should exist for clips
Currently for a clip we can 'Reveal in Project' and 'Reveal in Finder' - but just as, if not more useful, would be a feature to 'Reveal in Sequence' option, which would open a sequence (or sequences) in which the clip is used, and jump to highlight that clip in the timeline.

There is an existing way to do this, but does not use the "Reveal in" wording. In the Project panel tab, click the hamburger/wing menu and select Preview Area. This will enable basic clip info along with a Preview thumbnail player in the upper left of the Project panel.
To the right of the frame size info, you will see a downward pointing arrow and "video used x times". Click on the arrow and you will see all clip instances in your Sequence(s). Select one and it will open the Sequence with that clip instance highlighted.
Same option is available for audio, as well.
