options - set options per campaign. For instance, you can choose a
font to be used for all of your characters in that campaign.
filters - this lets you group characters within a campaign. The filter is the prefix to the comments for the characters.
sharing - if you click on the space just to the left of the 'delete'
icon (red X), you can mark a character as shared. This means that
someone else can import a copy that character into his account.
Typically a GM would create a couple of character templates for his
campaign and you would import that template as a starting point for your character.
copy - duplicate a character. This can be useful to create a
'snapshot' in time that you may want to come back to.
