Why don't you use supportcenter yourself? Then we can make issues or look at issues. Then we can see if some issue is assigned to someone and what the status is: open, in progress, testing, finished, closed. Then we also have an idea in which release something comes etc. You have made a good product, but it would be nice if we could get more information, as is mentioned numerously in other discussions.
Then you can add closing rules like: If an issue gets closed: Let the user add information about it in the changelog. It is only very little work each time and that also makes you not have to update it once every update comes out. This could also be done for the roadmap, then you don't have to manually update is completely every 2 years, but then every month it can be updated. It requires the enigneers maybe 20 minutes each month and is really valuable to us. We use the program to give as much customer service ourself, then why don't you use it?
Maybe if you would really use it yourself for our issues you will also face the problems that we have and therefore fix it earlier. Just my 2 cents
Kind regards,
