I'm writing this post on an iPad - trying to get used to some of the features - and to test whether I really need to buy the adminPad extension from the folks at JoomlaPraise.
One thing I noticed right away was the apparent lack of a scroll bar in the editor window. Turns out this is just how safari works on the iPad. One finger drag scrolls the whole page, two finger drag scrolls in the editor window -- or other scrollable areas on a site.
When I first discovered that boxes that should scroll just seemed cut off with no way to access the remaining text, I was checking out the newly launched site for Froggy Bottom Guitars. In an Ignite Gallery display, one of the players had submitted a rather long story to go with his photo. On a computer a scroll bar is obvious - but on the iPad, it was not.
