At first glance, it should be rotated clockwise by 90 degrees.

Presumably that is current state rather than design state?
Sometimes I make a pin change between input and output low.

Have them appear as tooltips? The most important legend would be
the pin names (e.g. RA4) rather than the package pin numbers.

Yes,
red = high output
green = low output
blue = normal input
yellow = weak pull-up input

No. I may need to simulate some situations in which an output pin is
being held high or low despite the driver latch not agreeing.

Not sure.
Warning: I'm not really sure what the "processor pins" feature does.
