The ?usescheme method is nice, but there is no way that I know to make it stick between pages. If I'm wrong about this though, please correct me. A user settable option would be nice so that a user could select between the 5 current LJ schemes (dystopia, bluewhite, lynx, opalcat woais) and the new one currently being designed.
The downside, though, is that perhaps LiveJournal will no longer have a standard look/feel if users are using different schemes. On the upside, users who are happy with dystopia won't have to get used to a new user interface if the new design gets approved.
Are there any thoughts/opinions on whether users should be able to permanently set their preferred scheme (with a cookie, or with a userprop)? Does anybody know of a way to do this with the current LJ code? Is there interest in this being developed if it doesn't exist already?
Thanks for reading and for the discussion!
