I want to filter out full comic pages from motd, but the tags.motd setting seems to support only one positive tag. When I add a whitespace or dash to that string, the motd disappears after reload.

"tags.motd": "one" - works
"tags.motd": "one two" - does not work
"tags.motd": "-one" - does not work
"tags.motd": "one -two" - does not work

Unsure if this works as intended... If yes, you could add a short info to config docs.
