XBMC and KODI both installed

but since KODI is newer, should I uninstall XBMC or doesn’t it matter?
installing add-ons with Kodi seems a bit confusing. Unless the 2 installed is making an issue for Kodi.

I also expected XBMC to be replaced by Kodi when I installed it, but now have icons for both. Is having both installed using up twice the space? Kodi seems to have all the plugins I installed in XBMC already set-up when I opened it, so I’m worried SSHing in and trying to delete XBMC may also break Kodi. Is there a way of removing the old XBMC code and icon without affecting Kodi?
