A personal todo list system that integrates with your email is also essential. I don't understand how people don't do it. It's all very well forges having status of MRs etc. but surely your job isn't only merging MRs on GitLab? So you'll have other todo lists distributed over various places like other forges, Jira type things and, of course, your email. Why not consolidate all your todos into one place? If you're interested in a patch, add it to your todo list and check the status of it periodically.
Conventions are good. It's part of being human. Learn how to use language to communicate with your fellow humans. It keeps the creative juices flowing.
