I am a dinosaur, and I absolutely depend on DEVONnote for my life! I love the .rtf storage files. I can edit them in a text editor to create new templates to use. I have about 5000 notes collected over the past 10 years. DEVONthink has much more than I think I would ever need.
My question: has anybody tested DN on Big Sur? I cannot afford to upgrade to it if it will fail to preserve my stuff.
