For those who may be interested, I wanted to pass along that I've released an update to the dialogs portion of JFXtras-Labs, MonologFX. I still have several things pending incorporation, but I made some structural changes over the weekend...and in terms of features, the big addition was that of timed dialogs - you indicate how many seconds they should be displayed and they fade in/display/fade out in that time without requiring user interaction. The effect is similar to an Outlook mail notification or OS X "popup".
More information (and a quick demo video that shows it far better than I can describe it) can be found here: http://bit.ly/18K5Uai
I plan to regroup and review some updates I completely forgot about as soon as I can and see where else we can take this. Thanks for your patience and prodding. :-)
All the best,
