...or may be it has even already been done (if that is the case, I'm really really sorry) um.. First of all, I must say that I don't actually have an AB yet because I don't have enough points to afford one yet, but I've been reading posts all over this site and have seen that people are suggesting using the ABs as humanly as possible to avoid getting frozen, such as, by setting longer refresh rates (ever 6-15 or more seconds per refresh) Well, so it occurred to me that you could make the programs do a random number of seconds per refresh instead of just one rate. Humans don't refresh again and again for hundreds of times at the exact amout of seconds anyway, it's kind of impossible, so if the program could do this it would be really nice and more human-ish. For example, maybe we could be able input something like: 3 to 15 seconds (random amount of time between more than 3 seconds but less than 15) and the program would do a different amount of seconds every refresh. ..er ... That's all. I apologize again if this subject has already been discussed.
That has already been done before, but at least you are thinking about good ideas. The problem now is that more people need to implement these kinds of timers to begin with, rather than using their simple refreshers.
the ABer that Ricky is making has alot more human like features. You should go check that one out in the submissions forum.
