if ya click that little picture of the touch pro at the top, there will be a section of threads that are "stickies" some of those are titled "touch pro essentials" i.e. hacks, changes, whatnot and " touch pro apps and software" i think that might be what youre looking for.
as for a thread with a running count of apps there is a software sub forum
