Just highlighting the territory and dice my mouse is over would be helpful to avoid misclicks.

when selecting a territory to attack with, highlight the territories that are able to be attacked. this would be a good solution to when dice sometimes block territory borders.

i think this would be a good addition, and i doubt it would add too much overhead to the flash app

.. or implement translucent dice .. cred goes to Jess13 for that one. translucent dice would rock!

a more app and graphic intensive idea would be to highlight all possible attack points when it is your turn, but that might be too much work (and use more resources) as a turn progresses and territories change hands.
