Couldn’t agree more!

Same here! Hopefully it can be addressed at some point, and the back button will simply close the picture instead.

Oof, sorry to hear it. Been there. In the future, be sure to click the “Backup Settings” button to the right of the “New Character” button (for client settings), and to the right of your character’s name (for character settings). Worked for me last time I needed it, anyway.
