TODOs: - make the tool work on Windows aswell - add -h/--help doc - give '-a' for audio only else video+audio - give '-v' for video only else video+audio - give '-p' for specific path - describe default behaviour - describe how to specify the path + show default paths - describe dependancies - beautify & finish readme.md - (later) validate python [check for python version] - make tool retry entry-when input is out of range or faulty - change behaviour when only one option is available by pafy (skip selection) - (optional) make file size string automatic (KiB, MiB, GiB, etc)
