Moving emails to a folder
i have hundreds of email folders, one for each customer. Is there a way to get the vertical row of shortcut letters in the move email screen like the one in the Contacts app? Currently moving an email on my iPhone involves a lot of scrolling. I thought about making an "A" folder for all my customer folders that start with "A" and so on and so forth, but this will mess up my existing archives.
