Yep, we still are! I recently got added to the ownership team for Kandan (
https://github.com/orgs/kandanapp/people) and I've been trying to respond to every issue / pull request that's been submitted. If there's a feature you are missing, let me know. Our last commit was 22 days ago, and we've added a ton of bug fixes, optimizations, security fixes, and overall tweaks in the past few years. Check us out!
Recently, the thing I've been focusing on lately with the app is bug fixes, small tweaks, and upgrading Rails. There's a lot of feature requests on the backburner, but I want the app to be extremely stable before going a mile wide and an inch deep.
That being said, "Let's Chat" looks like it is a great approach and I look forward to the progress that comes on it. The more open source solutions, the better.
