I think TreoGuard does a GREAT job of handling an incoming call. But the icing on the cake for me would be if TreoGuard could also include a feature for messing with the LED when you get an incoming message or call (or miss a call), e.g. set it to solid orange. That way it properly guards your Treo from unwanted call accepting, AND it also reminds you that something happened earlier, in case you missed it alltogether.
That feature is currenly in Butler, and it is the ONLY thing I use it for...would much prefer to see it in TreoGuard instead
