I changed some things I didn't like.
Installation: LargeUI 0.7 and higher uses the Mod manager for installation
Manual Installation: Open the file and extract the files into your installation directory in the /Screens/ folder.
The .dxpack is the modded UI, and the .rar file contains the originals. The different UI pieces are completely modular, you can pick and choose what you like and what you don't. Note that some won't work if you're running on small resolutions. Sometimes the intent is to use more screen space.
I moved the traits and equipment off the portrait. The traits now appear in rows of 2 so we don't have to scroll the list so much. Both equipment and trait lists are longer. If they reach the end of the list, the scroll buttons will appear.
I added another row for traits. The first row fills up first, then the second one. If both rows are filled up, scroll buttons appear like normal. I also changed so we see all the relevant stats, particularly spell resist and spell mastery that were previously hidden.
I added a full ring around an empty essence slot. The ring takes the colour your faction has (in screen it is red).
I also added the same ring as above when the essence slot has been filled. I love that the icons appear on the city HUD, but they are too hard to look at due to how they "fade out" at the top.

Longer spell list means less scrolling through it. Yes, the book looks a bit odd but more stuff on screen = better. The list was extended 250 pixels or 40%.
The following files are "nested", they go together to replace the main strategic UI. It is not recommended that you choose only some.
I enlarged the minimap somewhat (100 pixels width & 70 pixels height). Also End Turn button is larger. I have also extended the left context menu for unit selection and city selection in strategic mode by 200 pixels. This makes it easier to see traits for those units with many traits, also easier to manipulate the production queue of cities. There are also more commands available in the bottom action menu.

I recommend restoring all files to original before applying any patch.
