Agreed: what is best for X need not be nest for Y. We still use Simplenote -across 6 devices and 3 operating systems, and it is the only note taking app that my wife is happy too use. As for spell check: we use multi-language (English. Hindi, Marathi…) in the notes, so we did not even realize the need. For English — you are right, it matters, but the more recent versions do have that. Atleast in the V 1.4.1 for Linux that I use.
