Allow linking of more than one post to a proposal (i.e. adding of update posts)
Currently, only one post can be linked to a proposal (as far as I understand). This is the original post describing the proposal.
For better organization and accountability, it would be very helpful if the proposal creator can also link subsequent update posts to the proposal. This is akin to crowdfunding platforms allowing proposal creators to make update posts - and all update posts are easily visible on the proposal page. Here is an example: https://www.kickstarter.com/projects/boaeditions/lucille-cliftons-selected-poems
In our case, each of the updates would be its own post that people can comment on. And frontends can probably put all update posts under an Updates tab.
Another thing to consider adding is the total amount of funding received by a proposal up till current time (which I imagine will be less than most people assume due to the proposal not being above the return proposal 100% of the time). But I don't know if that has to be a blockchain-level change or can simply be done by frontends.
