I hadn't noticed the 2.0.1 update; just installed it ~~~ it surely can't be worse than 2.0 despite this particular regression.
Judging by results, I don't think there can be an ADE product test team, and not at all sure if there is a product designer either.
I use 1.7.2 for day to day use, as it is faster, easier to use and has fewer bugs ~ in particular 2.0 does not work with my Sony ereader in conjuction with Overdrive library books. I see that 2.0.1 hasn't fixed that bug.
A bizarre one ~ if the Sony is plugged in, I can't even read library books on ADE2.0.x, let alone transfer them.
