Slack Status TUI
Set your Slack status from the terminal, because opening Slack is how you lose 20 minutes.
Opening Slack just to set my status to "lunch" usually ended with me reading three threads and forgetting about lunch. This fixes that.
It's a small Go TUI. Set a custom status with text and emoji, save templates like "In a meeting" or "Focus time", and apply them with a couple of keystrokes. There's a plain CLI version too, if you want to call it from scripts.
Small project, but a good excuse to get properly into Go and the Charm libraries.
