Hi,
Here’s a suggestion: having a basic way to edit the photos while in the PhotoLibrary view.
The idea is to gain time just after importing photos.
To assess the quality of photos I feel I currently need to go to the customize tab, do some very basic edits - mainly exposure adjustments - then come back to the photolibrary to compare similar photos, often ending up deleting the picture just adjusted.
After all you can apply presets from there, so why not add an exposure slider for example?
