Just to echo the views of people here - I like many of the features of Evernote but to see red squiggles under proper nouns and abbreviations is unforgivable. People choose data management tools for many different reasons - for me, presentation is key. I re-subscribed today after a while away and was happy until I saw a few notes littered with incorrect corrections.
I've gone back to OneNote - where the spelling is configurable. And tags are now properly implemented.
I wonder how you guys think about value/effort mapping and the need for 'quick wins' now and again. Sometimes simple things are more important than USPs. I've always been transparent about product roadmaps - it's tough but it builds trust with your customers.
