I have used the pay version of Evernote for 3+ yrs, however, I will not be renewing. Because of the lack of this essential feature which is really basic table stakes for any enterprise "note taking productivity" app, I was swayed to check out One Note, which not only offers multi-color highlighting but other end-user friendly functionality that Evernote continues to ignore, I've now been converted. Sadly its goodbye Evernote!
My parting ask- How about you try to throw a very obvious much-needed feature bone to your customers every now and then and I might come back.
