I like the idea of a user guide being added, except I don't think it should be tucked away in the options menu. Maybe somewhere right on the front page as soon as you log in with your character. Maybe next to the Replay icon?? I don't think it should be labeled as commands though...needs a different term that new players can identify that this is where to go. Help Guide, User Guide, something like that.
I like the idea of more detailed explanations for options when you hover over them.
***I REALLY AGREE with the actual text for icons rather than just symbols. A lot of new players can't even seem to locate the shop without having to ask. ***
I also agree that the daily rewards/lucky boxes needs a bit more of an up front explanation. Maybe even an in game button that will link you to the website???
