If I want to make potions, I have to scroll through reams of ingredients, scanning the four possible effects of each of them for the desired ones I need. This is HELLA tedious and cumbersome. I should of course be able to search for effects directly, to make potion-making less of a giant PITA.
I think you can make potions by selecting the effect you want and it shows which ingredients you have with those effects (known). But of course the UI still need a major overhaul.
... which makes me wonder exactly how much time has passed from the events of Morrowind. Hundreds of years by the looks of things, but maybe I'm wrong.
The events of Morrowind were in 3E 427 (the start of the blights). The events of Oblivion (the death of the emperor and starting of the Oblivion Crisis) were in 3E 433, which also marks the end of the 3rd era. Skyrim started in 4E 201, so it's two hundred and some years after Morrowind and Oblivion.
