A Quiet Maintenance Week That Lasted 36 Hours

I planned a quiet maintenance week — no new features, just bug fixes after v1.7.7. It lasted about 36 hours.

I opened my own app to check something small and noticed Windows was still listing two GPUs: one RTX I actually use, and one GT 1030 from 2023 that's been dead for over two years. My PC was emotionally attached to a graphics card that doesn't exist anymore.

That one observation became Ghost Drivers Hunter — PC Workman now detects hardware that hasn't been used in 20+ months but still lives in your registry. Then, while fixing something else, I noticed idle apps quietly burning RAM for hours, so I built Background App Hibernation — drop apps to lowest priority or fully suspend them after 15/20/30 minutes of inactivity. You choose per app, it remembers, and it works with TURBO mode.

Besides the two accidental features

Scarred: I tried to have a "just fix things" week. But the moment I got curious about how my own app behaves, the brain started finding new features in the gaps between bugs. Also found and fixed a memory leak in the hck_GPT panel — the banner ticker was never being cancelled. A silent drain that only shows up after long sessions.

Huge thanks to the testers who spent hours breaking things I'd never have found alone — Przemysław, Kacper, Adam. (Also quietly jumped from 169th to 130th among the most active GitHub users in Poland.)
