Here's a aesthetic one that's quickly becoming one of my pet peeves *shrug*.On the shows episode pages sort the guest cast in order of importance so that guest stars are listed before co-stars.
There are two major benefits to this;
1) The most prominent and relevant actors in that specific episode will be listed first instead of minor co-stars.
2) The actors that will be listed are more likely to have a picture which makes the page look better without any big grey boxes.
Can you list a couple of example episodes where this is a problem? The guest stars aren't currently ordered randomly, but they are ordered by character appearances: the character with the most appearances will show first. You'd think that this would be enough to make sure prominent actors are listed before minor one-off roles.
