Hi Christopher,
there are currently no big plans. I will probably release a new version once all the acknowledged issues (
http://code.google.com/p/wwwsqldesigner/issues/list) are closed, and the release will simply be the current SVN revision.
So, if you are actually using SVN "builds", there won't be anything interesting / new in the next release, since noone has requested so. On the other hand, if you use the traditional release 2.3.2, you can watch what is new at
http://code.google.com/p/wwwsqldesigner/issues/list (I believe that latest release was done with revision 30).
Sincerely,
Ondrej Zara
