What kind of list-based plugin would you like to see?

I'm having a look again at this feature:

https://github.com/laurent22/joplin/issues/5389

The goal is to allow plugins to manage and render the note list. For example, we could imagine a plugin that renders thumbnails of the notes, or one that display the notes in a tabular format.

Those are just examples but I was wondering, if you are a plugin developer or user, what list-based plugin would you like to see or develop?

You can already see some ideas in the GitHub issue under "Example 1" and "Example 2"

It would be very useful to gather as much feedback a possible, so that we can get the implementation right from the start. Any suggestions or ideas are welcome!
