Now here we see a fully blown suite which is already alarming for basic testability.
Also, we had several apps targeting directly at Adobe in the past.
* Blackmagic DaVinci is the biggest, and it also bought several companies to start fusing a one-stop solution.
* Affinity also started with single app that got attention before being swallowed into Canva.
Leaving compatibility and ui-workflow (which is important to existing users), It's much more sane to start and focus on a single app instead of a fully blown package.
From Adobe/Creative Cloud users, I do know Acrobat Pro is one of the problematic apps they have in terms (it freezes, guess a lot of legacy code, etc). And yet, even where there is some competition on PDF editors, Acrobat is still strong also due to UX and features.
