Yes, but let's take for example the B&W Adjustment: of course if I hit it I'm expecting to see my pic turned B&W somehow and then start to modify it from there.
Now I have to hit the B&W Adjustment, nothing happens, and to actually do something I have to hit the Default tab, which brings me exacly where I would have been in the case above, just having required a click more.
I can see an added value only if you have your presets for every Adjustment that you want to apply instead of the Default one, but if that's the case, a more proper way to achieve that would have been to keep the "automatic" Default application with the regulation tab immediately open AND displaying also the thumbnail with the presets, so giving the possibility to override the Default setting by clicking it (maybe was already like that, don't recall honestly).
That way you would accomodate both needs in my opinion, without ending multiplying the clicks for whomever is happy enough to start its own edits from the Default level.
Of course you can get used to anything, I'm just pointing out that, at least for me, this is not for the better.
