This looks really nice, reminds me of Muzei[1] on Android which also allowed to add effects on the image that was being displayed. Definitely keeping ArtDiario running! Just a little thing: consider making the icon for the menu bar smaller, it's way to big compared to the usual size of the icons on macOS and it makes it look off [2].

For those who run Windows, I realize bing is a joke to most HN readers, but the desktop backgrounds they serve up are actually pretty great[0]. It's the only reason I keep the bing app installed on my machine.

I've been using https://www.artpip.com/ for years and was annoyed when they added paid features but I'd love something different. Are you planning a Windows version at all?

Love it, only I would really like to see an option to hide the "Art" icon in the top bar, mine is already pretty cluttered as is.
