Supported applications?

[Austin English]

Looking around the wiki/website, I can't find anywhere where the
'Supported applications' are listed (Powerpoint/Word/Excel viewer and
Adobe Photoshop CS 2, if I remember correctly).

Are these the only applications that are being targeted for 1.2?
Should others be added? Mozilla Firefox would be a great candidate to
add...

I ask, so I know which applications to make more strenuous appinstall tests for.
