Be able to save and restore the tabs complete with their existing queries, projections and sorting settings.
The description is in the attached graphic. The gist is being able to save the Filter, Projection, Sort, Skip, Limit settings for each tab as a logically grouped set of tabs which I can give a meaningful name to and perhaps stores them on computer as a JSON file and I can reload that json file after connecting to a MongoDB and restore my tabs.
Also, once you have this functionality, it would be nice since the application itself is written in Javascript to make a Microsoft Visual Studio Code plugin out of Compass as well so I can have it launch with my development environment where I am authoring code.

Hi Betsy - I am not the original poster, but also want this feature.
My feedback to your response is,
The current recent filter functionality does not help here as the devs are constantly context switching and when they do, they don't necessarily remember what collection they are in or what they were doing, but when they come back it helps trigger that thought.

Hi Eric, thank you for sharing feedback with our team. We recently added historic autocomplete in Compass version https://www.mongodb.com/docs/compass/current/release-notes/#compass-1.43.6. While it is not possible to save and restore full tabs, does this functionality help alleviate some of the pain?
Hopefully you're able to write queries faster now that your previous option values are suggested when you click into each text box.
Also, MongoDB has created an extension for VS Code: https://www.mongodb.com/products/tools/vs-code
