I've noticed that your very reasonable request for help has gone unanswered for some days.
This is not due to discourtesy, but reflects the fact a "quick and dirty" app with such a limited purpose probably doesn't exist any longer.
I note the other apps you use and Pixelmator is certainly a competent photo editor.
I suggest that you may need to reconsider your photo editing requirements and possibly go for a more comprehensive app which acts independently as well as being fully fledged Photos app extension - and a reasonable price.
I have posted in these forums in the past an exhaustive study I undertook to find an app that was at least as good as Apple's Aperture (no longer supported) but not so expensive or comprehensive as the full-blown Photoshop.
As a purely personal choice, my view is that, at $49, Affinity Photo app meets, indeed exceeds, those criteria. Standalone and as a Photos app extension this is a cheap (relative to the full Photoshop app) which does just about everything you could want.
Sure, it offers more than you may need, but the cost is good and the free and extensive video tutorials will likely take your photo editing skills to a higher plane.
NB I have absolutely no financial or any other interest in this company and my advice is based solely on personal experience with this app in comparison with several others, all of which I purchased.
Give this a read:
Affinity Photo - Professional image editing software for desktop and iPad
