I see. But the default ren'py's Displayable Inspector also lists the displayables from the back to front as well, right?
I think it makes the most sense to do the same as the default Displayable Inspector to not confuse users that way...
One interesting thing: sometimes I use guiManipulate just to get information about where in my file is this button coded XD especially in older projects where I don't remember things. I know it's not designed for such purpose, but I like the way it can tell me, for example, like this certain button is coded in this file, on this line. A simple 'tell me where is this' which is still on-screen. Well... I know Displayable Inspector does this, but I have a hard time getting used to how it's displayed in a whole new screen and covers everything I'm working on. So, guiManipulate kiiiinds of does what Displayable Inspector does as well nicely haha.
