Hi Tokyo, I suggest making a road-map that only goes 6 months into the future.
Anything beyond 6 months is puffery, no one knows what the world will be like 6 months from now.
Also, re: multiple masternodes at once:
Small update on this, it seems that running start all may fix this, I have had 3 nodes running without issues now but not starting them individually. May be worth trying for others with the same trouble on multiple nodes.
It appears the wallet locks itself after the start button is clicked, per the source code in masternodemanager.cpp.
void MasternodeManager::on_startButton_clicked()
{
...
pwalletMain->Lock();
Is there a reason this needs to happen? It seems more reasonable to only Lock() the wallet if it was locked when the method was called. At any rate, if you want to start individual masternodes, you will need to unlock your wallet after each click of the start button.
