What is most useful to us
The problem, not the solution. How you handle it today, how often it comes up, and what it costs you in time or money tells us more than a feature name.
What happens next
We read what comes in and group requests by the underlying problem. We cannot promise a date for anything, and we will say so if something is not planned.
Keeping up
New features appear in your account without anything to install or update.
