I feel the same. I also really liked the text input. The suggestions and autocomplete where also easy to use. And the block-based approach, with easy copying and sharing (through a URL), were super useful at times.
And for the AI part, the AI command generation (from plain text) was great. Also the follow-up command suggestions were handy sometimes.
Too bad Warp entered enshittification (already some time ago). Any (open source) alternatives for the good parts?
