Another Opus we're working on in c-lightning is dual-funding, so let's talk about that! This is Lisa's work, but I've been following along, and pushing to make it more general.
Today, you connect to a lightning node and open a channel, and you put all the funds in. This is simple, but it'd be better if you could both co-operate to construct a tx, especially if you could do it with multiple peers at once. This requires a generic coop construction protocol, which was fun to write...
It's 2021 and we finally got rid off Adobe Flash.
Maybe there is still hope after all.
