I would like an improvement on the menu "expression". 
Many users talk about this problem. We often work with the same tools and words. 

However, it is impossible to keep the library in order even when it is saved. 

With each use the order of the words changes and sometimes passes from one category to another, or deletes a category! 

Worse, it is sometimes doubled without knowing why! We waste a lot of time with this important tool. 

A stability of the Expression tool seems useful and to have the possibility also to put in alphabetical order the content of a category instead of having words in disorder.
Thank you for your attention.
