• Settings in the output modules (Book, Slideshow, Print, and Web) are “sticky”. When you leave a module and come back to it – even if you change the folder of images – the settings will remain as they were the last time you visited the module. This is an excellent addition if you’re working with one set of photographs and then move to another set of photographs and want the same output settings.
• In order to save output settings with a set of photographs, click the Create Saved Book, Slideshow, Print etc. button in the bar at the top of the creation’s preview area.
• Flash Galleries in the Web Module are now color managed.

Ooohhhhh, I like that idea ~ saved output settings. Thanks for the info Julieanne!
Hi Julieanne,
thanks for all your valuable tips.
Could you please specify as to how your second point (saved output settings) is different from the exising option in Lr 3.6 where you can save the settings along with the photos in (spcial) collection?
Having sticky output setting can be useful but now that LR has a color managed workflow it introduces some problems. For example, if a Proof Copy is created and edited to a particular profile, then that copy is taken into the Print Module, if the output profile that has “stuck” from the previous job does not match you have a problem. I would be nice if the behavior for proof copies would be to automatically match the editing profile or at least warn of a mismatch. And while it is nice to be able to create a Saved Print with all the output parameters, it would be helpful to be able to create saved sets of “Print Job” settings assuming that they will be consistent for a particular printer/ink/paper combination (and whatever “Print Adjustment” you have found to your liking) then easily applied to any image being prepared for output. Perhaps a “save setting” selection under the “Print to:” menu.
Excellent point and request. Can you post it here so that the product team (as well as other customers) will se it?

We are nudging people (more actively) now to save their “creations” in the output modules because of the change of behavior when you leave an output module and then return to it later. In LR3, of you have a collection of photos and make a slide show, then work on another collection and make a different slideshow, when you return to the first collection, it would return to the slideshow that you built specifically for it. It was magic for some customers – LR just knew that you wanted those old settings. However, for some, it was annoying as they would d have preferred that LR kept the most recent slideshow setting even if they changes collections.
In LR4, it is (hopefully) more obvious that you can save your creations in the output modules so that you can return to those specific settings with that specific set of images. At the same time, if you move to another collection ion of images, the settings will remain the same as the last time you visited. I think it’s a good balance of with options.
