Paper consolidates all your todos for you. Comments work well on images, giving you the option to comment on one or more specific areas of an image, or the image overall. Clicking on one image makes it full screen, and lets you flip through all the images quickly. If you paste several images in sequence, they form into a gallery. Media and embedded content is handled well. You can be notified when someone is reading your document, who is looking at it while you are, and of course what part of it they might be working on. This is table stakes in this day and age, but Paper handles it very well. Much like competing products, it lets you co-edit documents in realtime, and works across all the devices I would consider using. It works great with a number of popular services, and can talk to Slack. It is very embed-friendly, and very drag-and-drop friendly. It assumes you’re okay with writing in Markdown, which is pretty damn common these days, even if you’re not conscious that you’re using it.

And they don’t even appear until you make a selection. Toolbars are based on Markdown, so they aren’t necessary.
