For the "answer file" command LiveCode uses the OS-provided dialog on
all platforms.
They used to use a custom dialog for Unix, and still provide it as an
option in the Linux standalone settings so it's in there somewhere, but
it's not nearly as nice as the OS version that's now very well supported
with Fraser Gordon's excellent GDK integration for that platform, and
their custom dialog looks especially bad on OS X or Windows where it was
never designed to be used.
It's been a while since I've looked into the OS APIs for extending the
file selector dialog, and even then it was for Mac Classic so it would
likely be of no use today even on OS X.
But I would imagine that a similar set of hooks remain in modern APIs,
and that it may be possible to write an external for v7 that could
extend that dialog, or wait until v8 and use the built-in support for
calling OS APIs from LiveCode Builder.
For the here-and-now, when I need additional options for special file
handling I'll usually just use a sequence of two dialogs:
1. answer file to pick the file
2. Display the selected file in a second custom modal that provides the
other options I need.
I might be a bit smoother to have it all in one window, but apparently
customizing the file selector dialog isn't the easiest thing to do,
since I see at good many apps use a two-dialog sequence for such things
- at least we're in good company.
