Due to popular demand, here is a quick demonstration video of SleekTabs and how to add a new tab. It’s just under three minutes long and it shows you how to modify the example file (index.php that comes with the download) to add a third tab.
It’s only available at YouTube quality at the moment, but I’m working on getting a download to a higher resolution version up shortly.
UPDATE: full 640×480 quality in H.264/QuickTime is available here. 6.3 MB.
Also, if you want to see SleekTabs in action for yourself, check out this page which is the example file I modified during the screencast. There’s not much to see, but it was asked for.
Hope this helps those people who wanted to take a look before committing themselves to a download!
