[illegal site] have done it, so I thought it would be good for PortableApps too.
Basicly,what I would like is a program/feature of the PortableApps Platform that overwrites the default applications that open by clicking on a file with a certain file extension. It should also run when PortableApps Platform starts and exit when PortableApps Platform closes. Also, you should be able to moderfy what app extensions open with which program.
ex: HTML and URL files open with Mozilla Firefox Portable, TXT, LOG, INI, PHP etc open with Notepad++Portable
Just an idea.
