Ordering of icons on menu ... and sub-menus ??

Hi,

I've been busily building up a portfolio of useful apps on my flash stick.

It's a GREAT tool

However, I wonder if there is a way to alter the order that icons are displayed - what I would like to do is put the more frequently used ones at the top - but it seems to force them into alphabetical order.

Perhaps there is a way to do it, but I have missed it.

Also it strikes me that allowing sub-menus would be a useful way of organizing apps.
