John,
I am new to your PAM and like it's look and feel over all the others. Have read all the posts in this forum so:
Please may I cast my vote for you to include a method for adding other portable apps to your menu which allows us who already have our own directory structure on our USB drives to retain it.
I have been using portable 'drives' since the USB port was invented and have many console and windows applications on them in /Progs/ConApps and /Progs/WinApps. For my most-used apps I have a folder of batch files to start them. I would love to replace these with entries in your menu without having to move their folders out of my structure just for them to be 'found' by PAM.
You are used to batch files I see. I would get a free Delphi compiler (there are 2 very good ones) take the portable apps source (which is very simple to read and recompile) and change the requirement of PortableApps to your old folder. (Just changing a single string in a program, no killer)
