I would really apprecaite if one of you guys knows about one that could look like the one from oblivion or something at least better than the included in vanilla, as I find it really hard to search for clues about where the objectives are and who gave them after 2 weeks without playing... So yeah that's it.

As far as I know journal is not moddable except for the texture of the book.

If you have any of the expansions or GoTY editions, it expands the journals which shows active quests which makes it easy to keep track.

EDIT : TYPO

This. It's huge. Makes the Journal sooo much more manageable. In fact, given this update to Morrowind's Journal, I personally think it is far superior to the offerings made by TES4 & 5. Oblivion's relied too heavily on quest makers... remove them (as if) and the Journal becomes arguably useless. And in Skyrim... jeez... what did they leave in? The Skyrim Journal has a micro-speck of info in it compared to Morrowind GOTY's. I'd go so far as to say this: give me a Morrowind-like Journal for Skyrim, not the other way around. But then, I don't always see things the same way as others, so there's probably something I'm missing. Just my $0.02!

This right here is why I'm glad Morrowind still has such an active community. We can still play it with all of the features we love and not step on anybody's toes that prefers streamlining.
