This feature should allow the player to define a rectangle when placing textboxes in a GUI.
Also, when a new textbox is placed there should be an option to define what to do with the text that overflows from the rect. for example: In line or below.
This feature would allow more reusable GUIs, since you can easily store big texts and display them using the same GUI.
Currently, the text just overflows to the right and I have a procedure to split the text given an amount of characters per line and several textboxes, one per line, to have a proper format when displaying long texts in UIs but it's not very sustainable, it only works for an specific UI whit an specific number of lines.
