Does not work with enchanted tools and no line break
I really like the idea of giving the player more informations ingame in such a nice form - also useful to get the information about the uses for armor (remember that the durability is invers proportional to the armor_use in the 3D Armor mod ;-)).
But it does not give the actual values for enchanted tools when using, e.g. MTG with X Enchanting or Witches.
This is probably because it works with the original definition ("get_definition") and neglects overrides (in the tool capabilities).
And the GUI does not break the lines (for long descriptions or lists) and cannot work with line breaks in the description :-/
Mithril is probably the best material in the world of Lord Of The Rings, but this mod fails so far to give it full justice.
If you want to have Mithril ores and blocks being tougher than the diamond ones, with the block only dig-able by the Mithril pick (and blast resistant of course), try out my fork and tell me if you find any bugs: https://github.com/GreenDirkfried/moreores
