where is [X] KILL button ???

just tried jarvis version on Win 7.
WHY does this monster have to take over my computer ?!?
I eventually found some advanced settings, marked to NOT go full screen – but it still does !
and WHY does this – what is supposed to be a ‘media player’ have to try to control my whole computer ??
what appears to be an OFF button – wants to turn off my computer, as like the windows start button ?!?!?!?!?
It wont let me open task manager while it is running !
WHY cannot this player have a border – like all other players so you can customize the play window size ?
I very rarely use full screen on any player , so Why Default this video player to run Full Screen ??
and WHERE is the KILL [X] button so it can be Closed?; and those other window Max/Down restore buttons – like ALL NORMAL players or progs ?!?!
– the only way I found to close kodi was to [alt]+[tab] to take focus from the player and then right click the taskbar icon to close the prog … ! …
WHY when a video is playing does it have to have all the distractions running ??
– a streaming text in the bottom bar ?
– the controls and other unsightly menus etc.- all on top of the video play area ?!?!?
this player NEEDs to get back to the KISS principle – Keep It SIMPLE stupid !I
the Advanced Options are too limited – with no apparent ability to actually customize the appearance or layout of the player, etc.
it looks to have potential … … BUT ….
I have tried it , and uninstalled – until many improvements which need to be implemented … …
