I'm a fan of the posthog product but agree with the site. I appreciate the retro styling and all but opening all the windows for everything is disorienting and kinda breaks web navigation that we have all gotten used to for the past 30 years.
I feel the same way. I've used superpowers since I found it during the initial Ralph hysteria and love it. Every task I do starts with brainstorming and it always produces great results, even coordinating across multiple repos. Having the plan to read and comment on ahead of time is great, although admittedly maybe that is built in to the major harnesses now and I just don't know about it. Always feel uneasy kicking off a task without having used superpowers.
