Mine is probably more of a combo of things to streamline my workflow than anything else.

I use Sways multiple workspaces to segregate my apps into different workspaces for different tasks on startup of that app using the assign function in my Sway config. For example VS Code and one particular Firefox window always goes to Workspace 3.

I use the Layman Sway scripts to force all my normal workspaces to different layouts that is appropriate for that function. So workspace 3 with VS Code and a Firefox window is set in a 75/25 split with VS Code set to always take the bigger share. I can switch the two sides from largest on the left to largest on the right, or swap the apps between the two splits, or make a window full-screen with simple keyboard shortcuts.

Odd workspaces are on my left monitor, even ones on the right. This coupled with per workspace wall paper (all my windows are translucent, not for everybody I know) and particular tasks locked to predefined workspaces means I am never hunting around for something. Even if I did lose something I can use rofi to switch to it. If its an essential app I can use my keyboard shortcut that I use to launch the app, switch to it using swayr by activating the shortcut again.

I have used QMK for my keyboard to reduce the number of keys I must use to activate most of my shortcuts, and move them to my number row and home row using layers, double taps, and holds. I try to layer up the same family of functions on the same key but on different layers, so for example, the VI arrow keys move between windows, resize windows, move windows, depending on which layer I have chosen.
