Datastore Indexes should allow us to attach a comment that describes the purpose of the index.

Not sure if this is the right project to add this request to.

This would be extremely useful when maintaining a large project with lot's of indexes.

This. Currently we have to work out what an index is for based entirely on the fields.

Thanks for the FR.

As a workaround, you can add comment to your index.yaml file to describe the indexes. These aren't stored with the index, so you can't see it in the console, but it would be included in your source code.
