What new features in Lightroom 6 ?

I don't think layers are to much.  Some great plugins use layers. See Nik software, Color Effex Pro, Analog Effex.. We need layers so we can and another "curve layer" for example. We also need some PS tools like Levels. Contrast also must change. It's distorded the tone if you push in high. PS "Brightness Contrast" is amazing. Grain is very poor quality too. Another amazing too will be "Color Ranges". It will fly the software up. Brushes for mask isn't enough. We need more "dark room" masks style.

I suppose LAYERS would be too much to ask for since that would kill of the majority of why photographers still use PS. But it would sure be nice to have all of our photography workflow tool under a single host application! Photoshop is a great program, but it is simply overkill for photographers! Lightroom is the perfect post-process host for photographers without all of the clutter that we simply do not need!

it would be nice to have an identity plate that transfers across catalogs so the user doesn't have to re-do them for every new catalog.

Since I'm doing a lot of architecture photography I'd like to see improved tools for lens correction. A filter similar to "adaptive wide angle" would be very appreciated to improve my workflow within Lightroom. Thanks!

Many good suggestions in this thread. As a newbie, I can only add that I'd like to see the Book module include other sizes (i.e. Magazine).

My early 2011 15'' MBP has some bluetooth-problems with mouse when running LR. I did some research: I am not the only one. Perhaps Adobe and Apple could work this out now that Aperture is not an option any more???

Local edits of any of the dev modules, esp. HSL/Color, (similar to Aperture) would be a welcome feature. This would allow me to do much more on RAW-file, without adding a 200+MB tiff or even a bigger PSD on my HDD.

I'd really like to see perspective crop in LR. Very often I have to switch to PS, just because of the perspective crop tool.

I found a Plug in that shows you the focus point of your pictures.  It would be great to have this built in and turn it on or off with a keystroke.

Hoping LR does not go the way of subscription service.  I've already chosen a PS CS6 replacement and when CS6 doesn't work due to planned obsolescence, I'm getting away from Adobe altogether.  I can do almost all post processing via Nik's software, although a bit clunkier than PS, it's MUCH cheaper and the results are great.  Importing to LR is still painfully slow and some particular actions on large images are slow, even in LR5.  FWIW, I have a 2008 Mac pro w/ 14GB... Nik's software is fast compared to LR (and my catalogs are not large).

If LR remains a single, one-time price, I'd like to see Adobe enable panel separation for a second monitor.  Working full screen is much easier and enjoyable than having it surrounded by panels, even if they're on auto-hide.

-Enable straighten tool when zoomed in.

-Make it so that when selecting the first point for straighten that the cursor is a bigger circle with transparent center so one can more easily see exactly where the starting point will be for the straighten. The current set up of a cross hair for the initial point that then turns into a tiny little transparent circle, with a tiny transparent circle for the second point is very hard for older eyes and is not very exacting.
