One of the problems of an layout extension is the initialization time.
Normally the UILayout needs a couple of seconds to initialize (1-3). Depending on your server connection, your client hardware and your browser (IE6 is slow, FF 3.6 is fast).
To show a similar loading frame like the ExtJS Loading Icon http://apex.oracle.com/pls/apex/f?p=65555:1 use this trick:
Add the following code to the beginning of your Page Template Body or add a new HTML region (No template) on page 0:
After the initialization of the UILaoyut plug-in use the LoadingIcon plug-in with the option "Stop LoadingIcon"
The initialization feels much smoother now.
