I'm an Evernote Plus member, which means I'm a *paying* user. But because I'm not at the highest level, I get an "Upgrade" button in the Windows desktop UI. If I customize the toolbar and remove it, the button goes away until sometime later (or if I click some other button, like Sync).
I get why you would want to prompt free users to Upgrade and I think a persistent reminder in the UI is totally fair. But I'm a *paying* customer and I want to remove this item. I'm going to file a support ticket but wanted to see what others thought as well.
