[FR]: Use RSS guard normally when article filter pane is open

[cavalrymargarine0x1]

Hi!

I came over from QuiteRSS and have been enjoying RSS Guard so far. I'd like to request a feature where you could use RSS Guard® normally when the article filter window is open, because right now when it's open nothing can be done in RSS Guard until the article filter window is closed 🥴

Thank you very much! And have a great day!
