Louis has calmed down now enough to encourage you to have a look at the brand spanking new Preview of Opera 7.5. My Opera seems to be swamped at the moment, but it should be fine soon enough.
Be warned though you should read the warnings in the thread and install in a different directory for testing, and not install over the existing Opera install.
The UI is even more customisable now - and it now supports XP style skinning. Also changes to hotlist - now panels. More detailed changelog in the forum thread.
