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.
Same, README.md for most everything I can. Searching for info in the repo is also more productive than the search nightmare in jira/confluence.
GitLab employee here, nice to hear that GitLab is helping solve some of these workflow issues for you.
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).
