Since we now have a new version of wallet (thanks to developers) which fixes the major problem of extremely long startup time, I think you should upload this version to the official yacoin github... What do you think?
A link to sairon's build is here -
https://github.com/yacoin/yacoin/releases but if you mean adding the file as an attachment that can be downloaded directly from github, I can add that if it's helpful.
