Hi Phil,

If you want a category tree like in tt_news its easy to achive that.
You just have to take a look at how the tree is built in tt_news and 
apply that same principle in your own extension.

I've done the same for a custom extension. It took me a few hours but 
once you know how to do it, it won't take that long.

Take a look at the class class.tx_ttnews_treeview.php in the tt_news 
extension. Also take a look at the ext_tables.php file (search for 
'treeParentField').
