a.) I'm not convinced you know what the word hypocrite means.

b.) More importantly, they didn't ask for "numerous," they asked for one.

c.) Searching for the UI on, say Google, can have, at best, mixed results. Ive done this, then DLed and tried out the program only to find a completely different UI.

d.) The dev adding one screenshot to their readme.md and a /media folder takes them only slightly longer than it takes potential users to look one up and maybe get a good result. Multiply that time by the number of potential users, and it's obviously more efficient, and effective, for the dev to do it.

Stop being defensive. No one's attacking you or any other dev. They're making a request. Don't like it? Don't do it. Stop calling people names and trying to stir up drama.
