Windows: SmartScreen may warn about an unknown publisher — click "More info" then "Run anyway."

Click the menu bar icon (or press your hotkey), click a window, type your label. That's it.
Tags track their window at 30fps. Move it, resize it — the label stays put.
Cycle through colors with a click, or set custom palettes in Settings.
Tags sit at the same layer as their window. Other windows cover them naturally.
Set a system-wide keyboard shortcut to start tagging from anywhere.
Pick your shape, font, color palette, and tag size. Make it yours.
terminal --tags is free. No ads, no tracking, no accounts. If it saves you even a little headache, consider tossing a few bucks my way.
