I use PA as a way to always "bring my own computer with me", regardless of what computer I'm sitting in front of. As long as I have my phone, I can just jack it in and have all my software neatly available.
Now, to have "my computer" with me, it would be nice to also be able to save web links in PA, preferably in the form of some kind of (multi-level) menu, much like the one that pops up when you click Apps, probably best located among the various document type buttons. Clicking in the menu would launch a browser with the URL.
