Hi Chris.
I've been playing with the latest Photoshop and Lightroom trials, and on my 2014 Razer Blade, the 200% experimental scaling option in Photoshop is beautiful (and Lightroom seems to just work, kudos).
However, I've noticed that Adobe Bridge CC is still not scaling properly. This is a deal killer for me, unfortunately, because I rely heavily on Bridge + the Camera RAW plug-in for my digital photography workflow.
Are there any plans to bring high DPI support to Adobe Bridge?
