I really like all your ideas, especially the ones about the links in bios, copy/paste, organisation in character creation, and the loading screens. The only thing I'm sort of 'eh' about is the wipe chat feature idea. To check on any messages from a certain channel (such as group or whisper) if local is chatty, I usually just uncheck the local box, which makes the text invisible. At least that way you can still keep the local chat, while also being able to check other messages. But each to their own, I suppose.
Thank you for sharing these great suggestions! I enjoyed reading through them all.
