So, I've got LaTeX installed and up and running and it's wonderful (I can't believe I've gone 4 years of university without this... would have saved me so much time had I started with it earlier). Right now I'm using texmaker. Two things that would make the experience nicer for me. First, a real-time preview, so that as I'm typing, I can see the PDF output update. I work with a lot of equations, and it's hard to see the logical flow in TeX syntax, what with all the brackets and frac and whatnot. So a side-by-side code-and-preview setup would be ideal. Second, a spell-check. I'm using texmaker at the moment, and I know there's an ASpell dictionary that is theoretically possible to get up and running, but I'm not hardcore enough to manage to install ASpell.
