This is such a simple and fundamental feature that many users cannot live without, and it's a no-brainer to add it there into any text editor application. Come on Evernote. You know that this is easily done and you know many people want it. What are you waiting for?
Since version 6.5 it seems that Evernote has removed these shortcuts. PLEASE BRING THESE SHORTCUTS BACK. The font size shortcuts (CMD+, CMD-) have been so convenient that I find it annoying now that I can't change font size that easily. There is no reason to remove them in the first place. Thank you!
