Like most things featuritis, there’s a bell curve of subjectivity in this topic; the age old pantser vs plotter dichotomy. There will forever be churn of pkm folks moving thru the pkm space in a random fashion. Threats here in these forums are just noise. Most of us here are long haul Obsidianites!
In early stage writing mindset, I want to write (edit mode) and maybe some basic revision and editing as I go (more edit mode). All of this is on the fly; quickly get the main ideas into content; the 80% if you will.
During later stage revisions and final drafting I go into a more focused and thoughtful reading (reader, audience) mindset. This is where I spend much time in preview mode, pondering how the missive will be received, and sometimes hopping into edit mode.
For me, I’m trying to get out of one size fits all; don’t need no wysiwyg. It’s just distracting, for me.
Am thinking it would take substantial effort to devise UI coding to offer a wysiwyg that satisfies everyone. I be very happy with the decision to pursue the mobile path before Typora like UI feature implementation; it is basic infrastructure to get fundamental cross platform technology in play. I have no doubt that what Licat and Silver do in this regard will be awesome.
