Hi @kmikkels, all,
First off, I just want to say how much I admire the idea behind your addon. For a long time, I’ve been looking for a way to better immerse myself in the lives of my ancestors by contextualizing their experiences with significant events from their era. Until now, I’ve been relying on separate apps and websites for this, but having an integrated experience is such a game-changer.
Your addon is already super useful, and I’m grateful for it. That said, I’ve been thinking about how historical events might be even better represented visually on a timeline rather than in a table format. A timeline could make it easier—especially with lots of events—to grasp their chronological flow at a glance.
Your work and your hands-on mentality to create an addon from scratch (without prior experience!) really inspired me to give it a shot myself. I put together a rough first draft of what a graphical timeline might look like. (Confession: I borrowed a fair bit of your code as a starting point. 
)
Right now, I’d love to hear your feedback on the idea itself. If you think it has potential, maybe there’s even a way to combine our projects down the line. Please bear with me if it looks a bit unpolished—I’ve never created an addon before, let alone a GUI-based one.
Looking forward to hearing what you think, and thanks again for sharing your incredible work
Warm regards,
Samuel
