For a note taking app, Evernote lacks the tools to aid in brainstorming. Something OeNote-esque where you have a blank canvas and can create text boxes around the canvas to organise notes. Perhaps I'm an isolated use case but Evernote for me is my preferred tool for writing drafts which obviously includes brainstorming. The linear structure of Evernote makes it difficult to organise these notes. My Pro subscription is also up because I required offline notes while traveling. Now that I'm back in a first world country, none of the current pro features are really helpful to me so there is no real need to continue my subscription. Some more advanced or 'Pro' note taking features would definitely get me over the line to buy another subscription.
