I made something similar using Hammerspoon on Mac. I make a list of tasks, one per line, with a time estimate. Hammerspoon will show the active task, the time elapsed, and the estimate on top of everything using canvas. It's helped me stay on task and be more realistic with my planning. If anyone is interested I can share.
