Yes! I keep one instance open for planning and projects in general (daily task lists), one for strictly legal, and one for personal notes and writing (as a hobby and eventually to monetize that). This is on my Windows laptop, and each ties to Simplenote accounts I can, and do, use on multiple other devices, most frequently iPad and I Phone. Each has its own Independent Cintanotes file. With the tags it can work very well.
My only gripe is that, when I need to reboot the Windows machine (after installs / updates), opening the multiple CN files is problematic. I use the new virtual desktops feature under Win10 (similar to the Mac desktops and KDE's desktops), and the window to open the file gets "lost." I would like to click on a recent file and be able to have it easily open in a new window instead of having it always replace the existing open file, which I want to keep open!
(But, once they are open, it works great! This is more of a UI problem than anything else. No major architecture changes are needed to fix this, but the fix would definitely add value!)
Thanks for the insights you're giving. We'll definitely take this into consideration in the new UI.
