Agreed, so what's the deal?
We're still trying to make the wallet work. Max and I are working on a fix for the current wallet and at the same time we're doing our best with the limited availability of our dev. We're also talking to a few other developers and discussing maybe adding an additional member to the dev team.
As for the slow progress, we know that it's our biggest problem right now. All we can say is that it won't always be like this. It's been a perfect storm of problems that have completely thrown us off track as far as timely developmental updates go. But we're still here and we're still working on it.
The problem with reverting to a standard wallet with static interest is that all of the coins that have been created through dynamic interest thus far would be invalidated. That's the only reason we're even grappling with this problem right now.
The test wallet is having similar problems with dynamic interest as the first one. One proposed fix was that we lengthen the time between blocks so that the issue of different blockchains due to the dynamic interest system is mitigated. So that's where we are right now.
