The plugin is great but has some issues, one of them is that the recipe viewer GUI is very outdated and looks tacky and you can't change it.
When you view all the recipes, they are all scattered around, would be nice if there were categories.
This plugin hasn't been updated since November 2019 and if you go down thru the reviews, the author has been active in the review section since December 2019, saying he "could add" and "is going to add" features that people asked for but 6 months later and still no update, not even a small feature update
It's sad because this and CustomCrafting plugin are the only top recipe plugins. CustomCrafting is by miles ahead of CraftEnchance but it doesn't support 1.12 and under. Instead of author taking advantage of that, he let this plugin die because "it's open source" but looking at GitHub, nobody submitted any PRs and there's two forks, one behind the original and one even.
If the GUIs would be updated and stuff like categories were added, you would think the plugin is premium, but unfortunely is dead because the author just simply doesn't care. If you plan to use this plugin, don't, it's not worth it. If you have 1.13+ server, use CustomCrafting, if you have under 1.12, use MoreCrafting. Both plugin are updated regualary and both authors listen unlike this plugin & author that promises stuff in the reviews but doesn't do any updates at all.
There's also reported issues:

That will probably not be solved any time soon
