I want to give Manuscripts a try, but two things stand in my way; I cannot import any of my existing LaTeX manuscripts and none of my co-authors use OS X (but the latter should be solved by import/export, right?). So I thought I'd try writing a proposal, which really benefits from being able to jump around sections, from the clean layout, etc., and I'm the only author.
Currently there are no templates for proposals. Does that mean that, in order to format my proposal properly (with headers, footers, page numbers, single-spaced, justified text, page limits, etc.) that I will have to export the finished proposal and do all the formatting externally? Or is there a way to control those formatting aspects in the absence of a template?
