I am looking for an alternative to EN. Used to love it, but in order to sync more than 2 devices, you have to pay $35/yr. now & the app is getting quite complicated. $15/yr to sync is definitely an improvement, though since Bear's using iCloud, I can't see why you should have to pay at all. But I digress. My main point is to agree with this thread & ask if there's been any progress since early December of 2016 when you said you were looking into it? As one solution you could explore if you haven't found a good one yet, check out Wordpress. I use it for my website & in their editing interface they have 2 tabs: "Visual" & "Text" which shows the markdown (or whatever they use). Simple to switch back & forth. I think the only time I go into text mode is to troubleshoot something that doesn't look right. I'm still too new with Bear to say for sure, but it seems like it could be an ideal solution if markdown could be hidden when desired & if the free version included syncing.
if I remember correctly I replied to some other thread but I don't have very meaningful news. We're still looking for the best way to achieve this, our goal is not to compromise Bear markdown nature or add an unnecessary layer of complexity for everybody. We tried a "view mode" which is basically a rich text view (or the current view without markers) which turn to the current editor once you go to "edit mode", but several problems emerged regarding scroll and cursor positioning between the two views.
At the moment I can't grant we'll find a satisfactory solution for this problem but we have some other tech and design paths we want to try.
