Hi Steve,

Thanks for taking the time to check in. I'm afraid it's true, we don't currently offer a Share extension for our Mac desktop app. With that said, I can definitely appreciate how handy this could be, and will make a note of your feedback for future consideration with the team!

If I can help out with anything else for now, please let me know.

Best,
