Oi, I'm just telling you how it is, and going as far as I can under an NDA (I'm a bit Microsoft too, and am writing this on an Apple-brand computer). I'm not necessarily agreeing with how it is in v1 and, for all you know, I may have screamed about this specific issue in the private beta process. You'll have to guess. Just back off.
People want to do things both ways for good reasons. If you can't understand that, you may be extrapolating your own particular needs and practices a bit too widely.
The original poster referred to originals plus derivatives, and that is what I initially addressed. When your output is 16 bit PSD or TIF files, for some people it makes lots of sense to keep the derivatives separately and find them via metadata. OTOH some people find it better to store them in the same folders - that's their prerogative and it's not necessarily bad practice. In any case I have always thought that a cataloguing application like LR should be able to spot the difference between raw files' sidecars and identically-named files but with different extensions. LR should make it equally easy to work either way, Adobe now understand this needs changing, and I don't expect this restriction will last too long.
The original poster referred to raw+jpeg shooting, and the same argument applies - some people do like LR the way it is, with the jpegs being managed invisibly. This can be if you wire away the jpegs to a tight deadline, and afterwards retain the jpegs only as reference. If I did a lot of raw+jpeg, I might be in that group, but I've no strong opinion. Anyway, importing both files, stacked, strikes me as preferable - in general, a cataloguing application like LR should be able to spot the difference between raw files and identically-named files but with jpeg extensions. LR should make it equally easy to work either way, Adobe now understand this needs changing, and I don't expect this restriction will last too long.
I find the tone of both your replies to be unnecessarily antagonistic. So instead of jumping down my throat, read my words a bit more carefully. Nudge nudge, wink wink, know what I mean, know what I mean, say no more, say no more! A nod's as good as a wink to a blind bat!
