I'd like to do something very simple: filter all the user stories for a given app by creator (i.e. show only the stories which I have created). It seems to be possible to filter by status and labels but not by this. I hope I am missing something obvious, because this is mind-boggling. Thoughts/suggestions?
As far as I know, currently there is no such filter available to search by story creator but sounds like a good enhancement. You can raise this as an idea / feedback with Mendix. For now, I reported this in Mendix community Slack in community_feedback channel.
