Why MKC needs these permissions:
GET_ACCOUNTS + USE_CREDENTIALS - needed for proper functionality of GDrive
MANAGE_DOCUMENTS - allows write operations on SD cards for Lolipop and newer
WRITE_EXTERNAL_STORAGE - copy/move/del files/folders on SDCARD
READ_LOGS - if any error encounter during some operarion eg. copy - such error is logged. U can use LogViewer to see what happened
BLUETOOTH BLUETOOTH_ADMIN - sending file over BT connectivity with car onboard radio
INTERNET - used by FTP / Samba / Gdrive / DropBox
ACCESS_NETWORK_STATE - used by FTP / Samba / Gdrive / DropBox
PHONE STATUS - for new prepared functions (Sys.info Donate button)
WRITE_MEDIA_STORAGE - seems like tablets with Honeycomb that have internal+external memory(=sd card) need this permission for read+write access to both memory
MOUNT/UNMOUNT - needed for un/mounting filesystems on rooted phones
SUPERUSER - some custom ROMS require this permission to allow roor access
READ_PHONE_STATE - allows to detect incomming calls and pause AudioPlayer


NOTE: I'm searching for volunteers to localize MKC to different languages like India/Hindi German Korean French... If u are interested let me know on mail below
