Just some coats of polish. The base add-on has been done for a while and was updated for 2.1 support.
Not yet.
I’m all caught up with custom work and have just been busy with my day job. I’ve actually just had some interesting developments on this front which will mean more time to devote to my XF stuff but I’ll detail that later when the details are all finalised.
My own sites and sites I manage will all be upgrading towards the end of this month, both Calendar and Tickets are required for those upgrades so they’ll be done by then at the latest.
For the avoidance of doubt, Calendar needs styling and Tickets needs some last bits of polish / testing.
