Expanding the Use of Kate to Potentially Replace Ulysses

Today I received a reminder that Ulysses was going to renew in January. I believe that's another £39 a year I can save. First question, then, how can I achieve a preview in Kate for Markdown documents?

Well, it turns out, easily, using the Document Preview plugin.

Granted, it certainly doesn't look anywhere near as nice as Ulysses. But I'm sure there's some tweaking that can be done to improve this. But, the initial question is answered.

One major problem, however, will be working on these files on the iPad. What editor would be best to use there?
