i think there should be an application that adds portable applications, that are not compatible with the apps menu... say you want to add like portable Photoshop or portable adobe illustrator well its not really compatible. well what about an application that adds a shortcut to that certain programs .exe and starts it for you and adds the shortcut the program makes to the menu...
for example you goto the program app adder... in the menu and you just got a portable version of Photoshop... well you click on that program it pops up and asks you to click on the programs .exe that you wish to make a shortcut to... well you click on it and it adds the applications shortcut to the menu, and it opens it for you...
i thought it sounded like a good idea... it may be harder to make than it sounds, but i dunno...
