I have written a new program called UBBStyles. This program will take your current styles files and let you edit them offline and then upload them. This is for UBB 6.3.X only.
Other screenshots are available on the site.
The reason for this is that you can see the changes as you make them and also have a better environment to create in than the UBB Control Panel.
The current version is in beta, so there will probably be a bug or two as well as I'm open to suggestions on the program too. I've only had one beta tester so far, LK. He has done a good job testing the actual program. The installer and soforth has had only minor testing, but all should be ok.
If you are interested in trying it out, please visit

Please give me your feedback good or bad(as long as it is constructive).
