I haven’t got the same experience in terms of the resulting html (.md) pages, but I read it as you mean the actual gitbook for Windows editor right? If so then yeah, it’s really lacking as a documentation tool - you can try to connect a github account to gitbook account and use their online editor, I can’t say if it’s any better, since they’ve problems with their activation system (suspending instead of activating). - plus, unless you copy paste the final results, (from a copied folder) you get a really messy commit history if you’re using Github for Windows.
