I like this, just tried your demo and looked at your roadmap. Would love to talk more if you have time this week about it. I've used all the major systems so I can prob point you to a few features not on your roadmap.
You can reach me out on Twitter @XCSme or send an email at support [at] uxwizz.com, I am always happy to get feedback and discuss ideas.
Currently, there are a lot more features planned than I have time to implement and I am also trying to keep the product from getting bloated. I tend to prioritize improving existing features over adding new ones.
Some must-have that are planned are: API (to store or access the stored data), webhooks and more tools to help with self-hosting (Docker images, dashboard access logs, provide or integrate performance metrics, alerts, etc.). The plan is to make the platform a one-click set-and-forget installation, where nothing should break over time, and, in the rare case it does, you get notified.
