Author here. We pushed 1.1 today. It was scheduled for release two weeks ago, but it was quite hard to balance adding so many new features with the influx of bug reports that followed our launch a month ago. Obviously, adding Python is a big one, but I'm most excited about the new symbol index, which reduces 10-second workspace-wide queries to under 100 ms. The agent also uses this index, so the benefits compound over long agentic sessions as well. FWIW I'm not quite sure about the black-and-white dimming feature. If it's not useful, we might remove it in a future release so please let us know!
Not a walkthrough video, no. The first steps section of the getting started guide is the best place to start (https://docs.rune.build/#your-first-steps). There are also a few short clips on the home, Go and Python pages.
Fair ask though! a short walkthrough is on the list.
edit: I think it's from all the videos playing at once, even when not visible. It should be fixed now.
