In older LibreCAD dxf the dimension precision are the same as drawing units precision.
If you change the drawing precision to show 3 decimals the dimension are changed. All are controlled by "$LUPEC" var.
In 2.0.8 drawing units precision are controlled by "$LUPEC" and linear dimension precision by "$DIMDEC"
If "$DIMDEC" are not set the defalt value are 4. You are rigth, this is bad, default value for "$DIMDEC" can be set to "$LUPEC". The same aplies to "$AUPEC" and "$DIMADEC" (angular dimension) I send a patch (it is very easy).

Linear & Angular zeros is unimplemented (only GUI part) these are controlled by "$DIMZIN" and "$DIMAZIN" angular part is easy but linear is a bit more complicated (no problem with decimal units, but imperial is another matter)
