First of all: thanks a lot for your excellent work, @Cake-san!
It works excellent on the latest Windows Store version, and also on the launcher edition.
A feature that I really miss: to expand the armor properties.
Better armors have 2-3 properties, which is visible and editable by this script, but I can't extend the slots - the maximum is 8 or 9, I'm not sure.
Previously (a year ago), by using another .CT file, I made myself an uber armor, having 8 properties - that can be edited without any problem with your script.
Just please add a single line, where we can change 2 to 8, for example
