CFEclipse’s tabbed editor is great, but occasionally I do make the schoolboy error of editing the wrong file, easily done when you’re “in the zone” and have 3 or 4 circuit.xml or index.cfm files open.
The “Link with Editor” option is a great way to show which file you’re working on by highlighting the file in your project tree. I hadn’t enabled this option on my new MacBook and had forgotten how I’d done it on my old machine, so after digging around in the Preferences for a while I noticed it’s actually on the Navigator toolbar itself. If you haven’t found this either - switch it on!
