It's another case of computer programmers lacking or ignoring real world guidance. GS could have adopted two other options...
1. Why do we even need to flag multi-line text? The text doesn't need two boxes, the default is always <measured value>, (which can be added back if it is deleted), but the editing should always go directly to multi-line text box.
2. Why not just handle the text like a Label and allow in place editing with a double click?
Considering Dimensions seem to have had a rebuild recently, it doesn't feel like much thought was put into user workflows or presentation quality. 🙄
