The Wheel of Fortune cue dot has been on all episodes so far but only at the end, not end of part one. I am surprised it works as a cue dot, it's not overly prominent and the animation is more subtle than the usual black and white flasher. Maybe by 1988 the end cue dot was less important that the middle one anyway. They were back to normal cue dots by 1989,

On some episodes, the credits will end and the Scottish Television endcap will appear but there is a jump in the audio, as if something has been cut out between the credits and the endcap or the endcap from another episode has been put on for some reason. This has happened on at least two episodes so far.
Angela Ekaette seems to be trying to build her part a bit. It always seems odd when she speaks to the contestants at the end, it's not needed, Nicky Campbell has already done that. I do enjoy the bit where she comes down the stairs at the beginning and shows off her frock though.
Apart from largely dropping the questions, it seems that Wheel of Fortune did not change all that much over the years.
