Yes, mostly. Only very old (not yet really working) Dual Scan I scanners
do not have the proper bits set. But I need overwrite marks in my device list
for those anyway, thus I "know" they are film as well.

Well, on non duplex devices "ADF Front" might be misleading
and people search for the Back option? Somehow I like just ADF.

I'm right now thinkin where an sepearte transparency switch
is not too bad, because I heared that there "might be" ADFs
"some time soon" that are able to scan transparencies. Since
the devices do not exist yet I do not know whether this mode
will just work due placing the lamp where it always shines thru
transparency or whether it has to be enabled. In the later case
a seperate "enable transparency" switch might be better
than the transparency source ...

Not for the "for the sake" changes like strings of modes, but for
certain parts of the coding, yes - these days. When you look
carefully on our homepage you will also see that due to our
relationship from the Linux work, Avision contracted us to do
the OS X TWAIN driver.

(but so far the balance of that work is not that black). Linux work
is more profitable than OS X stuff (so far for us).
