I agree LT-Spice and many scientific software have terrible experience. There is a massive opportunity in designing better UI and UX in the modeling/simulation space (Julia's market). I can't wait for the web to clean this space. I believe modern JavaScript and more ergonomic low-level tech will help (i.e. Rust, better C#). I'm skeptic though.

You want the component parameters entered for you. A nice UI is secondary.

Also LT-Spice being native desktop is great. No way the lock it into the cloud now.
