So very glad to hear about this, were excited when we heard it on Direwolf's SMP series, this is more less a suggestion/request, even without this is gonna be fantastic!
I would like to second all these with a couple minor additions, ofcourse
I can see adding all these as not being an option; but would it be possible to do something to the extent of a “Extra Addon's” config pack. That is really all that is needed I feel, a community standard package of config files, though a mod pack is nice; we can manually install them on our own easily esp with multimc. Getting everyone on the same page with the config files is another story altogether.
Side note: believe it or not, I have these + a few more all at once…. In the end they all play nicely together and make for a very full experience though setting up the configs can be... fun
