Mail Monitor: Left click icon to mark all read?

Now I see the problem. Currently this is impossibe. I'll make this feature in the next versions.

As temporary solution:
Create the file with name someting like "activatechrome.vbs"
with content:

Code:

Set WshShell = CreateObject("WScript.Shell")
WshShell.AppActivate "chrome"

Set this file as mail reader. This script will activate the chrome window and mark messages as read.
