I'm having a hard time thinking of use cases where the resizable components would improve usability / add funtionality to web apps. The samples on the blog do illustrate that the resizable components are "neat", but how are people using this to improve thier web apps?
The resizable text area in this forum for posting really doesnt improve the usability. What was the motivation behind creating these components? Can you list some use cases where they would be really useful?
