Any tricks you can suggest?
Display text lasts based on the number of characters. Add colors to the end to make it longer (waste more string space, though).
"Parliamentary inquiry, Mr. Chairman - do we have to call the Gentleman a gentleman if he's not one?"
Ahh, I didn't know this. Thanks!
None.
I suggest you try making the messages shorter and simpler first, then resort to adding to the display time. People in general prefer reading more shorter messages than one big lump of text.
None.
