If you get around to adding panes to the mod, it would be a little more popular if they could also be placed into a crafting table and made into horizontal glass panes. This mod does it wonderfully, just not with any special glass.

Thanks for taking the time to look at this and hopefully including it in your mod.

Please add this feature to 1.12.2!

Yep, would love to see panes added as a feature also. Don't really care about the horizontal part as I've always had issues with that mod and no longer use it.
