You'll have to check in with them. But you can tag and categorize into folders. I bought Scrivener 2 and 3 because Word for Mac sucks, or it did suck a number of years ago (likely still does!) and I refuse to pay money for it. It's also like a giant digital journal and saves everything you compose.
The yearly cost for Ulysses is pretty damn low. Use the trial, see how it is, and subscribe yearly. Subscriptions aren't great but they solve a lot of issues over time and reduce headaches for support staff. I'm willing to state that $600/yr for Adobe's entire suite prepaid in full is a STEAL compared to the Master Collection costs of years past, which was near $3,000. That's 5 years of subscription, and you'll always be using the latest version of software.
The a la cartes are one price fits all, too. There's also a combo deal for PS and LR, with cloud storage thrown in. I interpret this as Adobe wanting everyone on their "drug."
