I definitely would love a way for the mod teams to like... flag threads as "issue being working on" or "rejected" or something, because it's hard to know what the status is (esp when i see threads pop up for things that i sent a report in for and the report hasn't been responded to)
i know part of the problem with dupe threads is that thread searching isn't widely implemented (i would not be surprised if either thread or tag search are one of the most posted threads in the suggestions boards and it's 100% because people don't go far back enough to find the answer, one of the reasons why i made the FAQ thread to hopefully limit the # of dupe threads)
piggybacking on this idea, i know some sites have this... idk what to call it, auto suggest feature? based on the title of your thread - if your thread has certain buzzwords, before you can submit it, it will show you possible answers/similar threads that might answer your question. that would definitely be harder to implement just the pill info though haha.
