Mark as read shortcut icon

Mark as read shortcut icon

Hello,

Please add an icon for "Mark as read" in Inbox. 

I am now using Zoho mail as my primary email and have other emails from Gmail and outlook.com forwarded here. Some of them are confirmation emails which I dont have to read but to simply mark as read and move to a custom folder.

It would be nicer if there's a shortcut on top instead of going through the menu.

Thank you.
