Hello,
I am still using this awesome tool!! One thing I think would be excellent is if you can set a line wrap width property for one or multiple nodes. This way, you wouldn't have to worry about manually hitting Shift+Enter when you're writing slightly longer node text, because the node would automatically move you to the next line after the set pixel amount.
This would make the functionality of the nodes themselves similar to the tables that can be added within the attachment function. I really love these tables because they automatically wrap and adjust depending on the text that is in each cell.
Thank you for considering this feature :)
