Hi David,
Thank you for taking the time to respond in detail.
I had heard of Scrivener, and had visited their site when I was checking solutions and chose Evernote.
So I just visited again their site now that I'm an Evernote user and know much more. What appears is that it can't be downloaded on Google's Playstore, so it doesn't seem designed for mobile function, except perhaps for Mac.
This is the big advantage of Evernote as already mentioned: On my Galaxy Note 8, I can work directly on my text, add notes, quotes, articles, pics , anywhere, anytime, at meetings or in a bus, and away from a table. Surprisingly, the Mobile version of Evernote is better for many things compared to the browser version on Chrome. I can understand that not all are happy composing text on a mobile (it depends on screen size), but then, when needed, I revert to the PC based version.
So, the subject remains open to you and others to provide their experiences.
Again thank you.
