Hi, due this bug that will probably never solved:
viewtopic.php?f=58&t=83259
Should be very helpful have the content_size of GUI elements readable in lua scripts. This value (pair of width and height) is available in the mouse hover tooltip(CTRL+Fx features) on GUI elements, so already exist somewhere, and have it available shouldn't create new bug, because the scripts can already "play" with gui elements size, instead, can help to fix some flows bad automatic re-sizes.
