gzm0 has started a total redesign of the application with a fully object oriented CSS based design. The efforts are well on their way and should result in a beta in the next weeks, probably end of October.
The goal is to make the application so flexible that including new changes is a piece of cake :-)
99% of all changes should be possible by adding a plugin.
Styles will be supported by rewriting the standard stylesheet. Plugins can add to the database and the goal is to make TAB embeddable into other web applications.
Custom lists (ranklists, datelists, etc. will be supported ba a generic list class).
Well there is still lots of work to do so whish us luck for successfully concluding the next release.
