The existing filter button within the card of an e-mail currently only makes it possible to create new filters, as far as I know.
Yet, this leads to a lot of filters that sometimes could just be grouped in the Logical definitions, by adding AND/OR conditions.
It would be nice to be able to edit those existing filters directly from an e-mail instead of going to the settings and pasting whatever e-mail address or topic should be filtered.

Cheers
