Give each job its own desktop
Mission Control shows every open window at once and lets you split your work across desktops you swipe between.

Instead of piling twenty windows onto one screen, give each piece of work its own desktop and move between them with a swipe.
Swipe up with three or four fingers — it depends on your trackpad settings — or press ⌃ + ↑ to open Mission Control. Every window on the current desktop spreads out, and the Spaces bar along the top shows the desktops you have. Click the Add button at its end to create another one, up to sixteen.
To send a window elsewhere, drag it up onto the desktop you want in that bar. Outside Mission Control you can also drag a window against the edge of the screen and hold it there: after a moment it moves to the next desktop.
Moving between desktops is a swipe left or right with three or four fingers, or ⌃ + ← and ⌃ + →. If the gesture does nothing, check it in System Settings → Trackpad → More Gestures.
