This is difficult to describe, but I'd like to see OO have an interface like Omnifocus or iTunes, with a sidebar where I could select and view my different outlines. I use OO for lots of different things, from to-do lists, presentation preparation, writing, grocery lists, etc. I end up with lots of different outlines scattered all over the desktop. Sometimes, I have to cycle through a lot of windows before I find the outline I need to work on. It'd be nice to have them contained where I could just go to a sidebar and select the one I need with folders for organization. I'd also want to be able to open outlines in a separate window in case I needed to see more than one at the same time.
