As it stands right now I have over a quarter of my inventory reserved for the various fishing bait you need for the discipline. Since these are considered tools for the discipline rather than just reagents, I think it would be a fair suggestion to make the Bait & Tackle skill actually open up its own inventory that holds only bait. An inventory separate from the primary one in order to maintain the dozens of baits used for each location. Its far more items than you have to carry for any other discipline and since the Bait skill already have an interface for this, I imagine it wouldn't be impossible to implement.
