Without reading all the past replies, I have a few comments.
It would be nice if the world selector to the right remembered my selection. Seems it logs me in all right, but to get to my skills data, I have to constantly change this selection.
In addition to this; if your viewing a server that you have not imported skills for, maybe it would be nice if it said something like "No skills here, you have skills on World X, Y and Z".
An additional option of showing only jobs I can do; or jobs within X labor points of my current skill set would also be nice.
Secondly; the new options on the personal jobs page, for me, simply makes the process slower. I understand the benefit of it calculating what you have and what your using to allow the user to see if he can achieve more with what he has, etc. However, again for me in my position, and I expect many others (mainly newer players that only have what they are wearing) - it would be nice if by default if applied the bonuses of what I was wearing.
Some data about the classes would also be useful. It wasn't until I needed to select one that I found where the information was in game. And since there is no official help page on the matter, it would have helped if it where on your site; since I was looking there for everything else; seems to be the only part that is missing.
And finally; good job on the site - 'tis very useful!
