It's not big enough for all the current tabs, let alone Mods + Mod characters, that usually end up glitching it.
Ex. AnR added Critters, Cartography, Shadow (Maxwell-exclusive, but used in a lot of mods), Sculpting, etc
At the moment Critters, Sculpting and Cartography all use the Ancient tab's space
The idea is basically to extend it 4 tabs, so we can use all tabs at once & have one space for a Character-exclusive.
