I may have missed the deadline, but I'd like to post my idea regardless. I actually just posted it and @abh12345 suggested that I post it here. So, here's the link: https://peakd.com/hive/@moeknows/i-would-like-to-propose-a-proposal-to-propose-proposals
Basically, my idea is a proposal system specifically for ideas (pretty much the same as your post). Users would be able to support ideas in the same way they would a proposal in the DHF. It would be based on accounts instead of stake. It would create a target to which developers could develop and use to justify DHF proposals.
