Hi!
Just bought a Cood-E TV and really liking it so far while i work out how it all works

I have some questions:
1) How do i enable CEC on the Cood-E? On my TV it's enabled, and it used to work fine with my old WD TV Live media box
2) Quite often, say 10-20%, a key press on the remote control doesn't seem to register, while sometimes it registers 4 clicks at a time. I point it quite directly towards the Cood-E. It makes the device feel a bit unresponsive. Is this a known issue?
3) Might be a stupid question, but here goes: how do i restart/reboot the device? Some add-ons ask this, but it is unclear to me how to do this. Pulling the power plug every time i need a reboot seems a bit of a hassle.
4) Is it intended design that the ports on the device are a bit recessed into the device itself? I have tried 3 different HDMI-cables but all of them are very picky when it comes towards processing the signal from the Cood-E towards my TV. A slight movement of the devices makes my TV loose HDMI signal...
Some bugs/weird things:
1) In the Get Add-ons section, what are "Kodi CZ & SK Doplnky" and it's deprecated XBMC-counterpart? I can't uninstall them, as they reinstall themselves back every time, even the one that says it's deprecated and should be uninstalled.
2) The add-on "Install Add-ons by language" has an update available, but it doesn't update. Well it does, but then it says there's still an update available... at any rate it doesn't go away from the "Available Updates"-section.
Any help would be appreciated! Regards;
