"Close" button is bad for UX

[samtuke]

I've clicked "close" a few times now, and accidentally deleted all my changes in the template editor. I don' think "close" serves a useful purpose, given that the window handle has a close button built in on most (all?) window managers.

If the "Close" button needs to stay for some reason, you could: 1. Move it somewhere other the bottom right, where I personally expect to find the save / done / complete / progression button, and / or 2. Add a warning if there are unsaved changes to catch folks like me who click it by mistake. Thanks.
