Regarding the next build, I've made a ton of improvements and fixes based on your feedback so far. I still have a couple more things I want to do and then I'll push a release. Should be working on it for a good portion of tomorrow so hopefully I'll make headway then.
I'm also now running the latest build of the addon on a live big board and so far it's working well! Thank you guys for the continued patience and support. I know it's been a bit of a nuisance getting this far but we're almost ready for prime time.
Sorry for the late response, thought I replied to this. It is currently being developed alongside feedback from testers and I think it's close to a point where I'll be able to mark it as stable. I use the add-on on a large forum and so far, it's holding up well.
If you're interested in purchasing, feel free to submit a ticket here and I can take care of that for you.
