Thanks @gazumped 🙂
As I said in my previous message my main gripe is that the new interface is painfully slower than the old one. I'm a "power user" of a PC, I've been a software engineer since the early 1990s, I expect things to get faster and better with each iteration. I can see that visually they improved things in the step up from version 6. I never looked into it, but I suspect that that they re-engineered the whole GUI system from scratch based on a different underlying platform - I'm guessing the old one was written in C++ and the new one switched to some kind of Node.js / Browser object, so of course performance went through the floor. Someone, somewhere, won a big p*ssing contest in a boardroom and convinced them that the new solution would be better, but it wasn't. Not only was the new front end klunkily slow but they abandoned features that I loved (in particular import folders - I almost gave up on Evernote at that point) and somehow made the searching facilities feel worse. If I was a paid consultant working for them I'd write up a 10 page document highlighting all of these things in order of priority - but I'm not, and anyway I am sure that they know these things already... it's just that (I suspect) their new architecture has painted them into a corner, and they can't get out of it.
Now I read that they've been acquired by an Italian mobile App firm. I guess it's a "watch this space" situation. I'm just glad that there's a CLI tool which lets you download your entire data set in a nice XML format - I've been doing that monthly for years in the expectation that one day this software will die and I'll have to migrate elsewhere. It's a bit like watching a slow speed car crash (the current situation at Twitter springs to mind!)
I'm not really looking for performance tips because I think the problem is the platform itself. For reference I'm on a reasonably fast 3 year old i5 with 24Gb RAM and SSDs, running Windows 11 in a "light" way (I don't allow lots of third party services to run). If something like Evernote 10 can't perform well on this, it should have been quietly smothered at birth.
