Hello Carlote, welcome to the forum.
Capslock is the written equivalent of shouting loudly. Except there is no benefit, since it is not "heard" more easily, rather it's harder to read. But like shouting, it's rude and unnecessary. So please don't do that.
Alex is part of the pak192.comic development team. All his creations go straight to the development branch of the pakset, and you can be sure to see them in the upcoming version 0.5. As such, they are not addons to be downloaded, but rather a teaser for the next release.
We do not have a set schedule for the next release, just an idea of what we want to include in it. The only date ever given was christmas 2017 in an attempt to stop questions for the date, and I'm still positive we can make that!
