Adding an announcement to one of my Blackboard sites with the new Google Chrome browser I noticed that the text area control has a grow-box feature. This enables you to drag a text area to make it bigger which is particularly useful if you have to enter a lot of text into one of the small Blackboard announcement boxes.
I can also tell you that in Chrome [and presumably Safari], all text areas on any web page have this facility turned on by default!
Worth the price of admission for Google Chrome? You tell me: it’s a nice usability feature that brightened up my Friday!
