Forwarding a wish from a reader of German Wikipedia:
Some articles have very long tables. It would be helpful if those tables can be filtered. (They can already be sorted, but filtering would be even more helpful.)
Example: https://de.wikipedia.org/wiki/Liste_von_fossil-thermischen_Kraftwerken_in_Deutschland
This is a very long table and it would help readers to filter the table, e.g. by "Bundesland".
