Thanks for the reply!

1.)

If I'm not wrong, users must vote directly for proposals like this one, the system does not care about proxied votes (proxies are simply used for witness votes).

I haven't looked at the code, but based on https://steemworld.org/proposals, I believe the proxy setting does apply for proposal voting, too. If you click into any proposal on that link, it shows influence from both owned SP and proxied SP. It also shows voters with no influence because their proxy hasn't voted.

2.) Nice to see that fundition.io is being developed. Thanks for the update on that. I always liked the concept.
