I've installed 0.3.0 and have been testing it out. The only thing I had to fix was Q/History marking. Other than that I haven't encountered any issues with the script itself, including using the new +S options.
However, I did encounter an odd thing. The old default SAB address was "127.0.0.1:8080", and that's what Sab Tab's default is too. This new version uses "localhost:8080". It should be a distinction without a difference, since localhost should resolve to 127.0.0.1, but on my Vista Business machine the address 127.0.0.1 would not work unless SAB+ was configured to use it instead of local host. Neither Sab Tab or Firefox itself would bring up the pages. With some experimenting I found if the server was set to localhost then only localhost would work, but if it was set to 127, either one would work. To reduce problems I've set Sab Tabs default to localhost and
if you are encountering "Sab unavailable" errors then try changing your SAB Address to: http://localhost:8080 in SabTab->Config->SABTab Prefs If anyone knows of any other issues with 0.3.0 please let me know.
EDIT: I see the changelog indicates SAB+ 0.3.0 now has the API I mentioned earlier. I'll look into using it, but for now you have to use the default template if you want to use interactive stuff like Sab Data, active Queue menu, and Q/history report marking.

That comes from the template. Apparently someone with a keen eye also notice and fixed it with the default template for 0.3.0.
