P: Provide a large preset preview when you hover over a preset

I'm easy - whatever works...

Sorry, let me clarify. I didn't mean it should be restricted to users with dual monitors - the second window can be used on a single screen.

Obviously updating the main Develop display is the ideal case scenario, but bearing in mind that the Develop preview works differently to the Library previews, I'm just putting it out there as a potential compromise.

I think it should be possible for 1-monitor users for sure. An option to use secondary monitor would be nice too.

The main LR viewing window. Efficiencey

Thinking about the possibilities of how this could work, would using the second window for your larger preview work for you?

It amazes me how fast Lightroom can provide previews of so many different presets, but bigger would be nice. Maybe define a zone in the preset list such that rolling over the left zone displays the small (and fast) preview and right zone is the big (albeit it somewhat slower) version, or something like that...

Indeed. there does appear to be a topic problem. 🙂
I have not submitted a post on PS yet but there is a good example there. In the Photo filter adjustment layer, I can scroll through the filter options and see them in action in the large viewing window. I am requesting the same for my numerous LR presets.

Um, it says you're talking about Photoshop. Are you referring to Lightroom instead?

Is ti possible to be more specific? I have looked at the LR and do not see what you are saying. It appears you are talking about the side by side window option which still leaves me at: ctrl z, ctrl z, ctrl z, ctrl z.
Would you agree that an option to simply hoover the mouse over the preset to see the optional preset in action without the need to apply it would increase production and the ease of use?

Did you know that you can change the size of the preview in the preset lists, using the menu to the right of each preset list?
