Feature request - number lines and tree summary and hidden files.folders summary in tree view

[d4rkb4sh8]

Could you add the feature to number lines - like the nl command. As piping it to nl and losing the useful color output sucks.
Also if the nl added feature could also be maintained while using a tree view,

secondly when using a tree view I quite like having a summary like the tree command stating the number of directories and files at the bottom.
You could even take this a step further and distinguish the number of .hidden files as a separate point which would be really nice.
