Custom Tab Titles

[peter-mghendi]

Hello there 👋. Excellent package!

I'm interested in having the option for a custom tab title instead of "Start Date" and "End Date." A simple string parameter would suit my needs, but I'm unsure if it would be better design to implement this using a Widget. It's also possible that someone else's use case might be better served by using a Widget.

I'm willing to contribute a pull request to add this feature.

Thanks!
