Describe your idea
Lists which can storage many variables inside and can be picked from a list which could open up a whole new opportunity for people wanting to make menus with lists, these lists could hook into text files to show your to-do list in minecraft and anywhere else on your computer, if this is the case the text files could be grabbed from the web making something like a friend system possible which again, opens up a new opportunity for people.

To expand the lists could be modified with a list like the audio list where you can choose an index etc.

You could view the lists in a new menu at the FancyMenu menu(confusing to say). Variables could also be created and edited here, sort of like an update to the variables

Hi! So you want to be able to pick values from the list, right? Because normal text lists (non-interactive) are already possible. You can get text from a web source and display it as text element. These text elements are scrollable.

I mean have a list system like python's which gives each variable a index and then anything can grab the whole list, one item from the list or the length of the list
