I came across your software a few weeks ago when I was looking for some kind of locally hosted collaborative documentation suite for internal use, basically, a wiki that can be used by people who aren’t programmers. I was a bit incredulous when I found that it is basically expected to use markdown if you want to have a wiki. This really raises the barrier to entry and restricts users to ones that are technically proficient and have the time to learn and deal with markdown. Wysiwyg is a necessity.
Easy content insertion is also necessary. We haven’t yet integrated bookstack, but I don’t see any alternatives (sticking with the locally hosted requirement)
