delete files from computer and playlist and easy move between tag fiels

moving from serato and traktor deleting several files together was very easy. 

in serato - cmd shift delete

in traktor - right click, delete from collection and ticking the also delete from computer.

in rekordbox there's no option to delete several files. 

rekordbox is considered to be easy to manage and sort music with it so i guess it's only logical that there will be an option to delete files with it.

also i would like to propose the option to move between tag fields easily (in serato cmd + arrow key) to move between artist/song/bpm/etc .. makes it much easier to use rekordbox as managing software.
