Are you serious? I see 5 symbols up there. First is a box, for selecting mail. Next to it is an arrowed circle for refresh. No Problem yet. After that it's 'More', which is text. No problem telling the difference there. The others are eon the right hand side, clear chevrons next to numbers telling me where I am in the list. The last is a distinct settings cog.
You need to open a message. There will be a icon showing something toaster-like with a down-arrow in it, a roughly octagonal surrounding an exlamation mark, a trash can, a pull-down button with a folder, and a pull-down button with a label.
Two of those icons make no sense at all (the toaster with down arrow for archive, and the octagon for spam). One makes no sense in the context of Gmail. It turns out that it is actually for manipulating tags just like the adjacent pull-down menu.
Am I missing something?
