The xlinks extension now supports bato.to and comick.io chapter links. Both can show country flags and support tag filters like the others. Bato's page counts seem to be loaded in by their Javascript, so I couldn't find a way to get that info through xlinks. But comick.io lets you choose some alternative language titles like Mangadex.

Also, if you use the tag filters, then the details pane (that appears when you click the icon or site tag) should show you which tag or genre tripped your tag filter.

If you spot any issues, let me know. I didn't test every possible combination of settings.
