I'd love to hear what alternative outlining tools people are using on Mac. I sometimes would like to make an outline, and I go off and do a search (I found Workflowy that way as well). And every one of the tools I find has significant problems. E.g., in Workflowy, I can't have two sections of the outline open at the same time. And Workflowy seemed to be the best one the last time I looked.
So, what I do instead is make my outlines in Markdown format. I tend not to have to share my notes, so this works pretty well: They are plain text, which means Evernote has NO problems with them, they are readable by me; if I need to format them I can load them into a Markdown formatter (which I never do, actually); and I don't have to worry about multiple bullets on the same line. Which, btw, if you've dealt with other web-based editors (remember that Evernotes have to be editable on the web) you know they ALL have this problem.
This is because, fundamentally, HTML is not a robust format for word processing, even if it's OK for presentation. And make no mistake, claims earlier in this thread to the contrary, outlines *are* word processing - there is formatting meta to the content itself. If Evernote wanted to solve *that* problem, they could create an all new robust word processing module, raise the price by $100 and lose a lot of cross-platform compatibility for about 10 years (that's how long it took Microsoft to nearly get cross-platform right with Word).
