Feature request: filter by operational status.

[bruceey42]

Thank you for making this great resource!
I have a feature request to be able to filter by operating status.
Suggestion would be 3 options:

1. Operational
2. Planned
3. Retired

I considered "Decommissioned" but actually the decommissioning process could take decades after permanent cessation of operations.

Hi @bruceey42

Glad you like this tool!

This was indeed on my todo list. I'm not sure about the "planned" status cause for many of these (DEMO, K-DEMO, ARC, ...) no one knows their future location yet.

But still a "operational" vs "decommissioned" would be great.
