Nice, it's much more clear to a layman like me! (Not the gp)

Nice, that actually looks really good. I was not expecting that.

Usually when there's no screenshot or video for GUI apps I assume it's because the creator is not proud of it, so a sign that the UI will be shit.

We spend a lot of effort on our UI and UX. I dare to say it's one of OpenRocket's defining features. There's still much work to be done though.

This is one of my favorite things about HN.

I'm into rockets, and clicked the link earlier today. I shared the suggestor's view, but didn't bother to post. I came back now, saw the comment thread had updated significantly, noticed that OP had addressed the suggestion, clicked again -- and noticed, hey wow, there are cool screenshots now, these are a lot more interesting, this is better than I thought!

That is a big improvement.

A short looping video of the software in action might also be good. But a lot more effort.

The screenshots looks great, definitely helps someone unfamiliar like me get a feel for what to expect.

The product is much cooler than I thought. Great update.
