Visual cues for headers

Congrats to JG on the v2.0 release and hello to everyone,

Is there a simple way to force the rendering of headers so they are more distinct from each other?

I have difficulties with documents that have a lot of subtitles since the top-level elements (indicated by a single “#”) become obscured by their lower level offspring. This is specially difficult when I try to move things around.

(please be patient, noob here)
