Same for me, here: I loved OmniWeb and used it for many years as my standard browser, but over the last year I became more and more frustrated and began looking for a replacement.
The most important features for me are:
• Good, user definable handling of cookies, site-specific preferences.
• User definable ad blocking, including complete blocking of flash.
• Workspaces.
• Vertical tabs. The thumbnails are not important for me, but I often work with 20+ tabs, which makes horizontal tabs unbearable.
I think I have found my OmniWeb replacement now: iCab. The handling of cookies and plugins is even better than with OmniWeb (e.g. session cookies can be seperately activated, plugins can be deactivated for certain pages), filters are ex- and importable, and the iCab homepage features a default adblocking filter for download. The filter manager is a bit tricky to understand at first, and OW's site-specific prefs are a lot easier to handle, but it works and does so well.
Sadly missing:
• Easy workpaces switching. If you enable the session functions in the prefs, you can save a session which is just the same as an OW workspace. You have to chose a file to switch to another session, though, which makes the usage experience really different from what OW gives you.
• Vertical tabs. Hmpf.
I have proposed both functions in a mail to the author. Let's see what he thinks of it.
Best regards,
Christian
