According to github statistics there were 296 contributors in Doge's development. It has been more than a year sine last change was made. It is quite possible that in private space some work at some level might be carried out. When and if there will be need of any change or improvement in anything we will be seeing movement on it. This no move in market has been for quite some time this indicates breakout anytime.
More work should be done in deploying the wallet.
I tried to install both wallets, the full blockchain one with a bootstrap and the smaller one at the website. The bootstrap literally did nothing a bootstrap is supposed to do and it was taking about five days to sync before I turned it off. The other one gave me a Java error several times after I tried to install Java on that machine. I stake about 15 coins on three dedicated staking machines, so if someone like me can't figure it out in about a week, sure many others cannot as well. I don't have time and resources right now on those machines to keep it going because I'm making money staking other coins.
I hope the team or following make the wallets easier to install. Not talking about the two main devs, but like they say, sometimes it's top down that's where the influence is coming from. I have no way of knowing in this case. I love DOGE coin, incidentally, and use it heavily in my small volume daily trading. It would be nice to have a real bootstrap and install the wallet in a day or so. Maybe for some reason that means redesigning the wallet. Or, have some kind of fix posted for the common Java error that says it's not installed when you just installed it. I'm sure installing both wallets is doable, but not as easy as it could be. DOGE would make a nice offline wallet stash of value if it was easier to sync the wallets.
