Thanks for guidance...
I've checked the sort script and added a little function to solve an issue (titles starting with space).
So, I've wrote trim's functions to use in a hole project when needed.
I think we need this kind of script as global when we need to include some functions that lua doesn't support natively.
But I don't know the better way to add some feature to current script, maybe a pull request? where?
Anyway, I've wrote "GlobalFunctions.lua" trying to start a global place to put useful functions that can be used by all scripters later.
So, its allowed? can I upload into scripts section?
