2) ACR - I use the Finder as my DAM hence I do not use lightroom. Need mechnism to import RAW. Also, there are some features in ACR which are not in photoshop (e.g., Shadows/Highlights, Clarity...)
Opinion here, guaranteed to be worth what it costs you. Forget it. There is not going to be a camera raw import. You will have to jump through the Photoshop (desktrop version)-to-document cloud hoop to get your photos ready to edit in PS for Mobile. Adobe are heavily invested in that paradigm, and history shows that Adobe doesn't back down in such a case. See the Photoshop Classic/Photoshop CC naming debacle, which still causes confusion among users. Adobe officials said early on in a beta-testers forum that this disastrous naming scheme "could not" be changed. Of course it could be changed. They could change the name to Billy Bob if they wanted. What they meant was, our minds are made up, so get over it.
