Sometimes I use LibreCAD to make concept drawings. In such drawings, some dimensions are still open, they micht be alphabetic or even a formula.

When I use functions like

* aligned dimension,
* linear dimension,
* horizontal or vertical dimension,
* radial dimension, diameter dimension,
* angular dimension

I frequently want to replace the automatic measurement value taken from my drawing and replace it by a symbol, like e.g.

* 5.5 mm +- 1mm
* a
* a+b-c
* any text

To do so, I have to make a screenshot, delete the automatically measured numbers and paste my text. That ist very awkward and I therefore propose another set of such tools which

* draws the arrows etc like presently, but does not place numbers but rather lets me input some text instead.

Since there is space for another button above the current one for dimensions, I propose to almost duplicate its image. But replace the A in its current appearance "1.23" for the current functionality (returning numbers taken from the drawing) and label its sibling for textual notes with "abc" instead of "A" (the text being taken from an additional dialog element like the one for inserting text into a drawing).
