[Reno-Sifana]

Is your feature request related to a problem? Please describe.

Yes. Feature missing Unread Notification Count Badge in the Taskbar. It's very useful when there unread message such as Telegram Desktop, Thunderbird and so on. Some Desktop Environment such as KDE Plasma, Xfce and others have owns Unread Notification Count Badge in the Taskbar / Panel. Even Windows 10 and Windows 11 already implement this feature.

Describe the solution you'd like

I hope next major Cinnamon Desktop Environment Release already implement this features.
