> Fortunately, thanks to some kind commenter here actually, a few weeks ago I found Boostnote
And you've been that kind commenter today for me. Boostnote is the first suggestion here that actually seems feasible for me, properly cross-platform, the UI seems very well done, lots of customizations, and (if I understand correctly) plain Markdown storage, not yet another obscure unnecessary format that's unreadable without the app. I've been using Simplenote after Evernote started being too bulky and unreliable, but Simplenote is not quite polished and doesn't seem to be getting any love. I'll give this a try, it'll be really good if this pans out. Thanks!
For the reference of anyone reading this: unfortunately, it looks like Boostnote's mobile applications are currently "on hold", because they're known to be buggy and unreliable, and the old maintainer has left the project. That is a pretty major issue for me, though (hopefully) only temporary.
(Another issue is that it's not really "highly customizable" once you get into it - even though "customizable" is a proud part of their tagline - but at least that doesn't seem to be intentional, just some messy disconnected design of the Preferences page, according to an Issue comment on github.)
