Take a look at the attached picture - the property window on the left is the default property window, the one on the right is a modified version of it. Wouldn't you like a list of completed structures that grows as you resize the property window? I thought you might :) It's a nice little touch that makes a world of difference when looking at the plot details. And all it took was the changing of one little integer value - so there's hopefully not much that can go wrong :p
This is a link to a zip file that you can extract to your Istaria directory. It creates the directory structure and puts a single file in the resources_override folder with the updated property window definition.
I've noticed a few other places where this same modification can be applied to the interface, but I can't help but think if it's such a simple change then why hasn't it been done before now? If anyone notices any side effects from using this please let me know so I can look into it - thanks!
