I'm glad you like it!
There is not currently a way to disable the animation, but I can definitely add that in an publish an update as I think it would be valuable to have that option.
To import a table like that, you would need to add each option as a line in the import textbox and the click import. For something like this where you have an item being a result for more than one number (as with 'head' and 'toes' in your table), you will need to add them to the table as many times as needed.
So for the table you indicated here, you would put this in the import textbox:
Head
Head
Shoulders
Knees
Toes
Toes
That would create a d6 table with all the correct probabilities.
