I am continuing to work on Kan [0], a dev-focused kanban board that works via plain text files in your repository. I am finding it really useful for solo projects, giving a really simple way to get per-project Kanban boards that I can sync via Git. Since it's local only, it's really snappy, and given the dev-focus, it can offer some pretty nice workflows with local hooks, customization, etc.
The other project I am continuing to work on is Rad [1], a programming language tailor made for writing CLI scripts. It's not for enterprise software, it specializes specifically in CLI, offering all the essentials built-in, such as a declarative approach to arguments and generated help (as opposed to Bash where you have to roll your own arg parsing and help strings each time).
