Hi DTLow - I understand that I can do it from the Notebook page, but it makes a lot more sense to be able to perform actions by right clicking on the notebooks in the sidebar. I shouldn't have to navigate away from what I'm doing just to create a stack, or edit the name of a notebook - it makes a lot more sense to right click --> rename, or right click --> add to stack. If you want to stick with the no-right-click-anywhere model that Evernote seems to have these days, then at least put the button with three dots next to each notebook so I can perform actions.
The entirely of Windows is structured around being able to right click for options, so it's extremely jarring to have a program that omits the feature. It feels broken the way it is now.
