I tried a ton of task managment solutions. The one I ended up with is the one I used in the beginning.

A empty piece of A4 paper landscape in front of the keyboard. Write all the things you need done in the next n hours onto it.

Tick the boxes for things you did, cross out things you decided not to do.

This is extremely low tech, but the very obvious advantage is that the piece of paper is always in front of you, independent of which window, desktop, monitor or whatever you focus. Paper is always open, you can archive it, you can sketch things, put down notes etc.
