I sort of like the pathing algorithm -- it teaches me things about the game. But I do not like its user interface and I usually regret using it.
When I am feeling experimental, though, I try using it for my first movement in the turn. If I do not like what it does, I reload my last autosave.
Details: I have autosaves set for 0 turns between autosaves, so I get an autosave at the end of every turn. Note, however, that when I reload an autosave and then hit end of turn, my "previousautosave" and my "autosave" will be for the same turn, and this might bother some people - personally, though, this does not bother me because I do not like changing history, though I will make an exception with the UI does something "irreversiable" that I did not intend.
