For anyone wanting to use even bigger text boxes with
even biggerinterface making them compatible is simple enough, other wise you get event window cut off and the option not sat on the scroll graphic.

Both mods come in Zips, so either know how to edit AND save Zip contents/files, or, unpack/unzip both mods zip files.

Both folders have a sub folder called interface, open eventwindow.gui.txt from both.
Copy the complete first 2 entries from the bigger EVENTS txt file, they are commented
# Original Long and # Bookstyle event window, The 2 entries end on roughly line 768.

The same 2 entries in the same file, but from bigger INTERFACE, end on roughly line 790. Delete them both, and paste in the entries from the EVENTS file.

Save! Now we pack them into zips, or check the zips have save depending on how you decided to work.

Simples.
