Tried it, that’s kinda cool. One comment, maybe display the message on top left or above the cursor so you can read easier.

EXT email: be mindful of links/attachments. Sometimes we want to give the user a little feedback. "Saved!", "Please wait...", "Loading..", without having to resort to those bulky dialogs. For these use cases, we have invented MiniMessage. MM can display a small message at the current mouse pointer or above a specific control. Just paste the source code below into a UI project package and run as java application. It would be nice if this would make it into Nebula It would be nice if the message box could be round/square/balloon/closable, etc.. Let me know what you think.
