Will this plugin ever work for Redmine issues?

It's not very useful for my team, to be used on Forums only.

Same here.

Vote for issue will be great!

I also agree that will be very useful functionality. I want mentions also about using filters for this field/column on the issues list.
Vote! 👍

I also agree that voting on issues would be great, especially for features. Voting on features is probably the best way to decide which features should be implemented.
