The Alphabet picker is great, one thing I cannot work out how to do is to keep the alphabet picker in sync with the container scroll letter.
When I navigate left to the alphabet picker I would like M to be selected, instead the letter that was last in focus is selected so could be anywhere on the list.
Do you have any idea how to keep that in sync?

I get what you're saying but that is not solveable I'm afraid. The container with the alphabet has no clue of which letter is actually selected. If you really want to solve it, you can add a very complex focus condition to your skin:
StringCompare(ListItem.SortLetter,A) --> SetFocus(alphabetcontainer,1) etc. etc.

Another issue which I have had for a while but not reported is that the cast images fail to return (from the addon cast widget) when there is animated artwork available. Again in the screenshot above you can see that with Mad Max: Fury Road. When I select a movie without an animated poster the cast images display correctly. Very strange but is reproducible, checking the logs I could not see anything at all to indicate why/how that would happen.

Hmm, I don't see those two are related as the animated artwork is delivered through background service and the cast by a dynamic path in a container. Sure there is no typo inside your skin code somewhere ? If you enable the verbose logging for the script, does it in fact try to perform a lookup ? There should be a logline that the script is called with the getcast parameter
