The editor is now moved to a new main tab instead of the form changing its size. This should fix your problem.
Items are stored in a more complex way than I thought. I'll add all items with stars to the item list and remove the gold status feature. As a disadvantage it takes more time for me to find all the items. But in the end it's the best choice as well as for you as you don't need to play around with values instead you hundred of items to choose from.
I would appreciate if you could send me the savegame (all files in the save folder in the game directory) and please describe which character and which world you've chosen.
