Would it be possible to get a wordwrap = "YES"|"NO" for the iup.multiline and derivatives? I may have missed it, but there doesn't seem to be one in iup already.

Not super necessary, but it would be easier to edit missions and whatnot from the data dump if for only readability purposes.

Has this been implemented? Does this have anything to do with the HUD or PDA? Sounds like a feature for the PCC mission editor.

Has this been implemented? NO
Will it be implemented? NO
Can it be implemented easily? NO
Why?

the iup control does not have a word wrap feature. You could add a function to do this but it could fubar all controls everywhere and cause untold headaches with formatting.

What is the IUP?

So, it's a GUI-building toolkit that lets you code in C and Lua. I checked the wikipedia doc for clarification.

every thing you see in the station menu, plugins and the like is IUP controls. it's like the common dialog controls. In VO not all of them are usable nor area all features usable and you can only use lua.
