It's easier to have everything in their own thread, than to clutter up one thread and get lost in the data.
Splitting it means it's easier to search for, through and process, flag and mark read.
If they read your post once, and noted it down, coming back to see if you edited it based on other people their suggestion .. unlikely.
I recommend just creating a thread with the feedback, post suggestions separately, and report bugs in the appropriate place.
This way the title of the thread can disclose what it is about and easier to search for.
