First of all, this website is a major work-in-progress, and there is no ETA for when any given thing will work.
Second of all, I made all of this for myself. If other people find use out of it, that's cool. But in general, as long as something here works the way I want, and I know how to work it, I'm not too concerned on whether someone else is able to figure it out or would prefer it to work a little different. Maybe someday, but for now, I am too lazy.
That said, the goal of this site is to be an out-of-game tool that helps you keep track of every single thing on every single one of your characters that you could want to track. Normally, unless you take notes, you might never be certain what your lockouts are on each character, what currencies you have (legacy or per-character), what missions you've completed (including weeklies and dailies), your conquest points earned so far this week, etc. without having to go log in to each one and check. For those who don't already keep track of that stuff with notes of your own, this site will give you the tools to do so. No, there is no possible way to integrate this with the game itself to automatically update anything. You will have to manually enter every single piece of information that you want to track, and then manually update it before you log out of any character, if you want it to stay up-to-date. The only exception is weekly/daily resets - the site will automatically reset your progress on weekly/daily things every week/day respectively.
