Over 4 years of people complaining about just adding a simple option to manually set a thumbnail and it still hasn't been implemented. Honestly, Evernote is my most important day to day too and yet I live with this awfully limiting and flawed software, no colour coding, no pinning notes to top, no flagging, no custom thumbnails - all really really basic features that could be added in a week and would improve the Evernote software ten fold?!
