About a year ago I created a tabs page that allowed you to have up to 8 tabs on a page and each tab can have multiple web parts added. One of the features that was missing was that tabs were not sticky. If you refreshed the page it would always go back to the first tab. Well, I have found some time to add cookies so that it will remember the last tab you were on. This now make it much easier to edit web parts and to use tabs with document libraries and lists.
If you have implemented the solution already then you will need to edit the page with SharePoint Designer to add the code. Or you can download the latest version and implement with the latest version.
You can find the latest version and instructions on how to update your current implementation here: http://www.bitsofsharepoint.com/ExamplePoint/Site/TabPage.aspx
