Really would be great have some few edit tools available in future versions of PM, not much of them but
the few ones usually are used for fast editions such a as levels, or curves, tone, etc, a good place for them would be
in the preview mode as other dropdown menu together the info, crop zoom and Histogram ones, really when I have to edit several pictures I need retouching just few things, and this will avoid open them in photoshop, which means a waste of time as well as some problems with metadata when switch between both applications.
Edit tools together with the future cataloging feature, would allow use PM as the only one app in the daily workflow, this mean, for me at least, save a lot of time and computer resources , apart of some others troubles... so, PM becomes almost the perfect software.
Thanks
