By meaning essentials, I mean a good essentials plugin that is fast, reliable, cutting edge(Java 8 support, with Java 7 support too), performance friendly plugin?
Yes, I do know essentials is being ported to sponge, but it lacks some features like ItemFlags for kits & bungee cord features, to make essentials custom, you need to get the source, but all you want is to remove lets say [L] from local chat.
Why am I asking this?
Because I can get a team, that would create a plugin like that.
At the moment, no. Essentials is being ported to Sponge, Foundation (https://github.com/FoundationDriven) was a modular replacement but work has stalled, and if you want to check out CommandsOverhaul, erm… Feel free
there is already a Plugin made by @Lokio27 see here.
However there are not as many features as essentials and not as many as you mentioned either. So feel free to develope sounds cool what you want to do.
