US10 - The columns displayed in the panel of items are sortable, once that one is clicked that is used as a reference to sort the files on descending or ascending order

US13 -The panels should display in the top of the side the current path and also this should be editable with double click to change the paths 
Lets always try to avoid hardcoded values, having these paths defined inside constants it will be easier to maintain
