What desktop app design frustrates you the most, and why?

Hey everyone,

I'm working on improving my design skills and would love to hear from you! Is there a desktop app you use regularly that you find frustrating, clunky, or in need of a serious redesign? Maybe there’s a feature you’ve always wished it had, or a small tweak that would make it so much better.

I'd love to hear about your experiences with any app or software (for work, personal use, productivity, etc.). Your feedback might just inspire my next project!

Thanks in advance for sharing your thoughts!
