If I'm reading correctly this translates PRs into test tickets? Is that a workflow that a lot of teams use? We usually just flow the feature ticket from grooming to dev, to code review to QA, then release.
FYI we used to use Trello (using the same workflow) but switched to Jira and wrote this tool in the process. Jira aggregation in the web app can be quite slow so actually this tool makes tracking a bit nicer as well.
