do we really need this ?

for users who aren't used to using keyboard shortcuts, yes. bc Desktop takes up part of your screen (for users with less than one screen), this type of feature helps if you want to navigate a file and find a function (e.g., fix this xHandler function).

This is because I have reduced the resources of my operating system (Windows).
