Not to derail this thread, but I’m wondering if you might say more about MarginNote vs. LiquidText @PaulWalters. I just bought an iPad Pro mostly because I’ve become very enamored of LiquidText and wanted more room to work (and also because the Macbook Pros are simply too expensive for what they are). MarginNote looks similar, but with a Mac app and maybe more polished UI, with a heftier price tag.
