The option to create a community is only available if you login with Hive Keychain or PeakLock. Currently not possible with Hivesigner.
But thanks for reporting this. I'll do a small change in the next release to add a small warning message that will be easier to understand ;)
oh good. This was very confusing for a new user. Maybe hivesigner should add this feature..? It might be worth asking the dev.
There is no missing feature on Hivesigner. But to create a community and customize it the user have to sign multiple transactions. This is more complex with Hivesigner as the user will have to switch website and come back.
well, my point is that you cannot create a community with Hivesigner, so it's kind of not a useful tool for those who want to create a community.
