Oh.. opening the door to suggestions? Hehe.
1. The sheet you are linked to is the 1st edition sheet. 2nd edition is here:

2. If given the option between the two, I prefer the unequal column length. More room for notes on powers.
3. My favorite sheet so far is the Extended Archetype sheet in the Beginners guide with notes on how each of the powers works.
4. The Character Folio (basically an extended version of the basic sheet) has a really really useful section under the 'Attacks' section that allows you to list each of your attacks along with to-hit, effects, and save information. It makes it so easy to get right into the combat.
