Hello Doug. Are you meaning that the word "delete" is used instead of "uninstall"? In which case, I've just changed it. If not then please feel free to edit the docs yourself - it is a wiki and all are welcome to contribute Alternatively, if you can explain more about what you feel is incorrect then I can change it tomorrow when I get up (bedtime now!)
I think the bit about clicking the block number to see which courses they are in is correct although perhaps it could be better phrased - for example I have the number 4 next to HTML block but it only shows 2 courses when I click on it, because I have two blocks in each course = 4 in total.
