Just wanted to throw this out, see what people think: I'm working on bot for GitLab/Slack/Jira that helps with development workflow. It can assign merge requests, send you reminders on slack, nag you if you stall with code review too long, change Jira statuses to 'code review' and there is planned a lot more stuff. We use it at company that I'm working for currently and it was born out of my need to automate some of the mundane/annoying stuff during code reviews.
So far any validation for this idea comes from my company. People were requesting that I add more functionalities.
My only fear is that there are products out there already that are basically doing the same but for free (with downside that you have to host it yourself).

I would make a list of all the other tools that do something similar.
Find users of those tools and ask them what they love and what they hate. See if yours can fit in.
Always, be very careful to add more features, If everyone wants them maybe you add it.
