There is no real order of which issues get done. Everyone is welcome to contribute any feature/fix they find important.
I just work on things I find have priority which is mostly bugs first. The next big feature is probably backwards compatible API which is a huge amount of work.
There is a issue for the creation of communities. Already but it doesn't specify exactly it. Like where do we add this in UI, do we make a fullblown screen or just a popup. Which logic for showing this creation menu. Some instances don't allow users to make them. etc
It didn't enable by default in this update. But I think when it did get added it was with default enabled but that was a while ago. I can take look at changing this default.
That issue with firefox is not one caused by Jerboa. So that would need to be reported with FireFox. The only change we did was add support for FireFox.
Can you expand on this?
