I'm aware that Mystical Customization already has this as a feature in 1.14+. However, will this mod back-port that feature on top of it's own ability to create seeds via the config files given?

[Essence Color/Tier Color/Tier Name would be controlled by the hex value and name provided, like the crops would.]

On a separate idea, could created Tiers essentially have their own Tiered Inferium Seeds? [Which would be configurable, in-case people don't want that.]

[Edit] It would be kind of interesting to see created tiers also have an option to add ingots for the respective tier as well, could probably do some interesting stuff by using a mod like Pewter to [potentially] integrate created ingots into TiC. This is kind of a "After Agricraft is compatible" sort of thing.

One thing that might come up, as a note, is possibly people making seeds of tiered essences, this may need to be tested for if the same bug that occurred in here occurs in this mod. The reason I include that info here is because they could also try to make custom seeds of custom tier essences as well [Meta?].

Just something to look at after the Agricraft compatibility is fixed [when you have the time], and the main topic of the enhancement is implemented [also when there's time available to do so].
