For those of use who use a lot of metadata presets and development effects presets, it would be really useful and save a lot of time we would go organise them into expandable groups.
For example, my metadata presets include lots of information, and keywords linked to the location, and they are labeled by location (Greece, Dodecanese, Samos, for example), but I have a LOT of places within Greece and many other countries and so my list is now endless and growing and I have to scroll through them all to find the one I want. It would be much easier if I could group them by Country, and when I first see my metadata list, I just see the country.. then when I click on the country, it can show me a folder of regions, and then from there the places within the region... Just like Finder on a Mac.
The same goes for the list of effects presets in the Develop Module... it would be good if we could have folders so we could group our effects by need, eg, for portrait images like softening skin, rouge, eye brightening etc, and then for landscapes, etc.
Obviously the folder names need to be customizable!
It would really save us a lot of time in our workflow!
The same could also be applied to camera raw! You already have it within Photoshop!
