The dev seems really active on here and I've got a feeling over the next few weeks when he sorts out some of the backend challenges, he'll look into some of the UI/UX improvements. The site from what I can see runs off Laravel / PHP and it's on GitHub so people can submit PRs and help him out with work.
I'll be looking into it myself to see if we can get click to collapse nested comment threads working, along with some other UX aspects.
I think getting one of the app devs interested in kbin would be pretty handy though, but might be hard if the main dev is actively working and improving the site
Yeah.. I have/had a bad opinion about symfony, because we used it an old company. But that was mostly driven by young, inexperienced developers. In hindsight the problems we had were mostly because of junior developers trying to build tools instead of the framework.
