I'm not sure if the missing character traits are fixed yet. I wrote a script that can add them to old characters, but it required manual selection of the traits. From your image filenames it looks like 358 (Hair Style) and 362 (Beard Style) got added to Ylian Male Characters, but the Face trait was not. It may take a while to update all characters, people need to make sure they select the right trait, or all old characters will look different suddenly both in the client and in myplane.
MyPlane will not allow you to edit your character descriptions
a) Security:
MyPlane does not have the permission to alter the planeshift main database, so a security issue in myplane cannot lead to item duping etc
b) Scalability:
MyPlane is designed to work on a readonly DB slave except for its own database that keeps privacy data and a list of online characters
c) Consistency:
The psclient is how you interact with Yliakum and your Character, you should always be able to play the game without being forced to use myplane
d) It makes life easier for programmers:
Having to support different interfaces for doing the same thing and updating them always at the same time can be a headache
Let me say that i am not familiar with how some people have a creation info and some don't, changing it doesn't sound like such a big deal for me, but maybe there are good reasons that you can't change it. You will have to get the feature to change the creation info added to psclient if you want it.
