This workflow has historically worked for us quite well. We merge in features rapidly so having GitHub be the source of truth for activity that needs to be tested is beneficial for never accidentally missing items. 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.
