Atlassian Jira/Confluence SUUUUUCKS. They have given up on making anything better. I try to do as much as possible on Markdown files in a GitLab repo using Atom's Markdown preview (e.g., documentation). Gliffy diagrams are still OK.
For sure! One thing to take a look at might be markdown numbering rendering in the browser. E.g., if I use `1. 1. 1. ` I only get ones, not 123 (last I checked).
