Glad you like it, the changes are far better for using segments in particular.
Yes you can by using the http or mqtt bindings, the wled binding has not implemented them yet. See here for more detailed reply.
There is also a bug in the 3.2 stable binding which will be fixed in the next milestone or you can already download a fixed jar from the thread linked above. Please read at least 4 of my posts in that thread. Your probably wanting the controls because of the bug, so get the fix and it is less of an issue as the binding can turn the global on if it is off and you turn a segment back on.
