Not much to elaborate on, but I'd love to see this option available in InDesign as I frequently find it useful in Illustrator. When trying to align objects to the center of the text, as opposed to the text box (because the text box is taller than the text), this would be amazing.

Alternatively - a way to double click on the top-most midpoint of the text box and have it autosnap to the glyph height. This is virtually identical to the feature that already exists within InDesign.
