Depending on how it were implemented, this might be one issue, or more than one. The goal is to allow users to vote/comment on plugins more easily than by leaving the tool, finding the plugin on the plugins website, choosing "comment and rate" and then filling out a form. This could be solved with a simple REST call to the server, right from the editor. It would allow users to comment on good features/aspects of the tool right away, notify about bugs right away, basically, to communicate.
I've already had more than one case where I had to find the author's email (was not easily found), email them, wait for a response, go back and forth a few times...this was a bunch of extra work which for other plugins I've avoided--I just remove them and never use them again, which doesn't help the community.
Some places this might be integrated:
1) when disabling or removing a problematic plugin
2) when receiving an exception message related to a plugin "Blame...plugin" dialog
3) from the plugin dialog - not great, but a central place to add comments
Form would be the same as currently supported on the website.
