If I could do it myself, I would, but since I can't here are my favorite mods I'd like to see converted:
1) Weight Mod, that will let you carry extra weight. Yes, this is a cheat, but the only thing it cheats is pointless running back and forth to carry equipment from mobs you have already killed. (It is not a difficulty cheat, it just makes a game less boring.)
2) Some plant disappear when harvested and some don't. It would be great if they all disappeared.
3) Failing 2, they other useful time-saving mod would be Autoharvest, where all plants within a certain radius are automatically harvested and put into you backpack.
4) Any GUI mod would be great. When I played Oblivion years ago, I was using a font so small, 22 items could be listed in the inventory.
