Hey @asuleymanov,
Glad you like the service. Considering go-steem/rpc I usually add only what I need personally. I am expecting others to send pull request to fill in what is missing in case they need it. Is there anything in particular that you are talking about?
Considering the package in general I may end up doing some cleanup when developing SteemWatch further. I am expecting people to vendor the package so if I feel strongly that the interface could be cleaner, I will change it.
Where can I ask you a question about the package?
