>and instead focus on features and bugs

Who says they don't? They've pushed 23 new releases since 2025 with thousands of updates that include exactly the bug fixes, performance improvements and security fixes you're talking baout. This latest release, v157, includes the built in dark mode you're asking about (I just saw it on the popup on first launch when installing this new version) and the release notes describe improvements to tabs. v156 included huge performance improvements and they're regularly pushing tons of CSS updates across practically all of the releases.

I don't understand why people claim these things aren't happening when they're regularly documented on their release notes page.
