The better you document a request while remaining concise;
The more you demonstrate that you understand MC and have considered alternatives ways of doing something, and have adopted the way MC works.;
The less you are just expressing a desire or whim to manage your media some way, such as "How software xyz does it" or "How I always did it", such as browsing files by folder;
The more you have helped others on the forum;
The more likely it is that your request will help a lot of users;
Then the more likely your requests will be responded to and implemented...
...unless you just have a really good idea, because that is good for JRiver and all users, and will likely go on the list of things to do.
If you don't understand what MC is doing, and perceive a problem or shortfall in functionality, but don't explain that and just ask for new functionality to "fix the problem", your request will likely be ignored. If you're lucky a user will ask why you are requesting new functionality, and drill down into what you really need or mean. If you state there is a bug in MC without evidence and a repeatable set of steps, that produces the same result when other users or JRiver follow them, and state you need it fixed with new functionality, you will likely receive no response at all. But JRiver would probably look at it anyway, before dismissing your post.
The number of times I have seen requests for new functionality from users who joined the forum in the last day or so, and the post is their first or close to it, is amazing. Frankly, I think of those requests as just trolls or noise. Sometimes those people just need to learn how to use MC, search and read the Forums and Wiki, and then they are happy without new functionality.
Most requests don't get a lot of discussion, or even feedback, from JRiver but they still get considered and if good, often implemented.
Note that you don't have to use the Feature Requests thread. You can create your own thread and make a request. Give the thread a meaningful, easily understood title if you do. Some people preface the title with "Request:", but that isn't necessary. If there is no discussion about a request after a few days to a week, it is fine to bump (add another post) the thread, so it pops to the top of the forum again. Evidence is that all threads get read by JRiver.
