Truly neat; a few rough edges

What a neat app! Super simple to use with a great UI. It'd get five stars from me, if not for these quibbles:
1) I only want it to appear on a monitor of my choosing, rather than all connected monitors.
2) The default aspect ratio results in the logo being partially cropped on a 1080p monitor.

Relatedly, the aspect ratio seems to be affected by System Preferences' Fill Screen/Fit to Screen/Stretch to Fill Screen setting for Desktop Background (and I can set different monitors to use my preferred backgrounds as well), but all of those changes get reverted after a minute or two. If they didn't get reverted, this would be a 5-star app for me.

Thanks for the feedback! Multi-monitor support coming soon, as is something that should address your aspect ratio concerns.

What a cool idea

I had been using some dynamic Earth wallpaper for a while, but having real-time imagery is next level galaxy brain stuff. Thanks for a neat new wallpaper!

A few things I'd love: ability to have different views on different monitors, a "random" option (which would pull from any available source when updating), and I'm not sure if there's a NA view without political borders but that'd be sweet, too.

Gorgeous & Profound

A beautiful and thought provoking screensaver. A true joy to see my favorite planet in such brilliant clarity.

Love the menu bar access. Little things I'd like (after using for three minutes) Why not have option to auto cycle thru views? And is there possibility of a refresh frequency of less than 20 miutes?

Great work. Thanks for offering it to everyone.
