I've been here since 2013. i am not a programmer, but worked in IT.
i wish i could help. from what i see this is the problem. Bio has been managing the community,
but there has been no leadership, no action, or too slow.
And most of us here can't program. We can only give some feedback

is there any kind of roadmap?

i don't see even the 10 month renewal period bug changed. it should be a year...
let alone more advanced features.
i suggest integrate privacy features, maybe optional,
just copy the code of other coins...
that will spark use of NMC and attract attention.
