Having made the decision to use Evernote as my primary Notes solution, I am finding limitation after limitation that is revealing my decision as a bad one!
Not being able to have a stack within a stack (a 'sub-stack' maybe) is one such limitation. They could have at least thought about this issue, addressing it for example by allowing 'Areas' above stacks, for example. The fact that a fundamental note organisation limitation like this has been ignored is yet one more check in the 'con' column for me.
Another core issue is only allowing alphabetical organisation of folders, rather than allowing user choice in such a significant matter. And let's not mention the permanently black sidebar in so-called "Light mode". The mind boggles.
