Ciao. Love the minimalism of the menu system in PA. Its a very good piece of software design.
I have three requests, based on long term use.
1 - Make the menu box have STRETCHABLE length so that you can see more items without needing to scroll.
2 - I would really like a SECOND TIER of categories. So there would be Categories and Sub-Categories under them if you needed that. As the number of portable apps I am using increases all the time I am finding the single-tier category system is not quite enough to organise efficiently.
3 - I understand why you have "Documents / Pictures / Music / Videos" on the right, mirroring Windows. Personally I would prefer if I could have the option to customise them to be pointers to any location.
