Further to the comments above, I suggest you look at https://meta.stackexchange.com/questions/tagged/status-completed?sort=newest to see what requests StackExchange have been "completing" recently.
That will illustrate by example what kind of detail they like to see in a request.
Note that most of what has been completed (or accepted for development) recently has been 'bug' not 'feature-request' items.
There have been nearly 18,000 feature requests: https://meta.stackexchange.com/questions/tagged/feature-request
