Just wanted to remind you that the two issues I pointed out several months ago have still not been fixed.
• Square image cropping in custom icons (and attachments) is off about a quarter of an inch off. I did point this out in version 4.56 too.
• Still no way to delete custom icons.

Thank you for the reminder. Both issues have been documented. I'm not sure when the cropping issue will be fixed exactly, but we should have the ability to delete custom icons on iOS/Mac soon.
