Get a screenshot app. Shottr is awesome. CMD+SHIFT+CTRL+4 and I can take a picture. Paste UI on a GitHub PR. Paste Figma into a LLM. Paste bugs into Slack or a support tool. It does text recognition too, so whenever my wife sends me some kind of ID via a screenshot, I can just copy from that.
Chrome has powerful screenshot options built in. Open the web inspector, choose “Run command”from the dot menu, and then type “screen” to find those commands. Full-height screenshot is particularly useful.
