I can't use the *.jnlp of course, but I played with the test file you provided.
The reason why I wanted the text to have a fixed place, was the fact that I read in the forum that many people use SH3D to obtain a building permit. In such cases it would be interesting to have a fixed text block
at the right or
in the bottom right, where all the drawing info goes.
Of course, if I add or delete text the text block changes in size. Preferably, for latin script, the text block should be fixed at top-left, for arabic script at top-right.
