I can also relate - I'm a tech lead, and it just also happens to be I find programming to be an enjoyable puzzle. When my wife sticks on some TV, I'll usually scratch an itch with some problem I've spotted, or some improvement that can be made - most of our docker build time improvements are me trying out different things and finding what works - same with little QoL features.

Props to the dev of this project though - in some ways this kind of project is one of those 'magnum opus' things - not many people might know or care about it, but it's actually something to be proud of achieving.
