If they are similar enough (e.g. same color correction for shots during the same hour), or you have common needs (e.g. add the same watermark) then yes, it can save you time.

Perhaps, perhaps not. They add a lot beyond a "star rating system". Depends on how many pictures and how professionally you shoot. Sorting 2,000 photos shot on a newspaper, travel etc assignment, and picking winners, is no fun done manually.
>* Also darktable boasts the ability to export an image into GIMP. Is that really like a big feature that you can't do from elsewhere?*
It's basically irrelevant, unless you run Linux, or are one of the few that runs both programs (Darktable/GIMP) on a Mac or Windows machine.
>Isn't it just a Save then Open type situation?
Do it 30 times for 30 pictures and it gets old fast. Especially since you need to scout to where you've saved each time.
"Do I really need a star rating system?" => Not really in most use-cases, the flags are enough (rejected and accepted).
These days I use folders primarily for organizing tasks that must be tied to the filesystem, such as making backups, and for representing entire projects or super-categories. For anything more nuanced I just apply some of my 100+ or so tags.
e.g., if you collect “reaction” images, most images may show more than one emotion (angry, happy, sad, etc.), so you just lump them in one folder and tag each image with the relevant elements. Same for people and characters that may appear in more than one series, and images that will have more than one character, so instead of folders named after a series or character, you just have a “Movies” or “Anime” etc. folder and tag each image with the series’ name and the characters in it.
If I really need to get something done, I use Acorn (https://flyingmeat.com), which I like a lot. The support and documentation is top-notch.
I have used Pixelmator in the past and really enjoyed it. Best $15 I spent on a Mac app, hands down. I do dislike the "here are a million little windows" UI, so the Pro is kinda nice that way.
But I am not sure how this all fits with things like Lightroom/darktable. I know Pixelmator can easily edit RAW files. But darktable seems to be able to edit a batch of images at once so you don't have to manually edit each one. But should you?

tl;dr photo editing is confusing.
Edit: Also I just dug into what Pm Pro does, and it's damn impressive. Adobe should be scared.
