Snap textframe size to content (like double-click in InDesign)
A function appreciated by all in InDesign.. doubleclick the side of the boundingbox of a textframe and it snaps/scales immediately to the content.
I'm not talking about Type -> Area Type Options -> Auto-size

Robin, you can already do that by double-clicking on the "prong" (for lack of a better word) that points downward from your Area Type, which will toggle the Auto-sizing of the area.
There's also a checkbox in Preferences > Type to make all new Area Type objects auto-size by default.
