Hey All!
I needed to display some dialog boxes in a recent game and the old 9-slice plugin wasn't ported to v3 yet so I wrote one (github repo). I have a live demo here and a gif of it in use follows. Would love to see this get some use outside of my projects so give it a spin. I'm pretty active on the discord and try to check in here weekly so feel free to ping if you have any questions!
Happy hacking!
