That would be great !

Another question came up:
Is it possible to calculate the width of a text expression to improve 
the placing of the expression ?
Something like |GetTextExtentPoint32| on Windows.
For example to calculate from the width of a measure and the width of 
the expression
the best placement ? When I look at the code of your dynamics_horizpos.lua,
it seems like you hard-coded the positions (i.e. the widths) manually.
If this is not a function of the Finale PDK, maybe that would be a 
helpful function
that JW Lua could provide ?

After having coded just two days now with JW Lua I am really very impressed.
That makes plugin development at least for experienced software 
developers reeeeeeally easy.
Thank you very much, Jari !

Have a nice day,
Jan Angermueller
