I think it should be a user selectable option just like back in the Hughes days. With them you could pick thick guide lines that showed logos or thin guide lines that didn't and showed more channels at a time.
That would be a nice option, (something that could be added with any software release), however, it's not available to us yet, so we use what we have available to us.
They could make a lot of this stuff changeable, but remember, most people that have issues CALL in to D*, not come to a site to find answers, that means the 1st level CSR would have that much more to deal with ... aka read off the script.
That would cause more issues.
Possibly why the D* branded recvrs came about in the first place !
The Mini Guide that we have today came from the Hughes recvrs.
