Version history:
v0.01 Alpha version
- slow, looped through the display case every time
- browser stopped responding

v0.01 Beta version
- works pretty nice I think :)
- some ideas not yet implemented

v0.01 Initial release
- no longer pops up the question, just prints all kind of stuff without asking any questions
- added checkbox for hiding the information

v0.02
- fixed a bug occuring when case was empty
- fixed a calculations bug
- changed visibility -> display, which is much wiser when the list is long
- automatically inserts next 10 items to boxes

v0.03
- fixed to work with Firefox 4

TODO: 
- Check for script updates.

Feel free to develop further.

Questions? Feedback? Want to develop this PoS further? Please, contact Tykinruoka (#875019) a.k.a. TrashF @ QuakeNET, IRCnet & netgamers.
