I've created a Chrome desktop shortcut which I'd like to continue to use for my emails (I can't or don't want to switch browsers because I'm using a number of chrome add-ons). My tab favicon shows the number of unread messages (Gmail lab feature) but the icon created in the taskbar doesn't change or update accordingly.
I'd like the shortcut icon in the Windows taskbar to show the number of unread messages in my Gmail account (similarly to the badges of some add-ons).
There are a few stand-alone applications (e.g. Shellscape's Gmail Notifier Pro or Wavebox but they'll add another (unnecessary) icon to the takbar but will open the inbox in my default browser, not in the pinned window. And all of them work only if I allow less secure apps to access my Gmail account.
It's of course possible to change the shortcut icon. So it was my idea to link it to an unread icon which automatically updates like this one. But I don't get the script to work and I guess security would be an issue as well.
An unread count in the system tray will have to do if I don't manage to get the shortcut icon to update periodically. Ideally a Chrome add-on should display it (again to avoid adding another application). Inbasic's "Gmail™ Notifier" lists as features: "Get unread message notifications on Windows taskbar notification area (system tray)". But I didn't get it to display a system tray icon (neither in Chrome, nor in Firefox or Opera).
I think a number of programs's desktop clients are basically modified browser windows (e.g. Whatsapp)? Whatsapp's icon changes. So there must be a way to do it?
Any suggestions what else I could try?
