Hello,

Previously in Plasma, I had managed to display in the task bar, a tab displaying the evolution of operations, especially when copying and pasting files, ....
This indicated precisely the details of the operation, the time remaining, ...

After a complete reinstallation of my system, I can no longer install this function.
The operation appears well in the notifications, but I wish I could make it appears in the taskbar.

Thank you for your help.

When doing such operations in Dolphin, the Dolphin button in the taskbar displays a sliding green shade (with Breeze dark theme) showing the progress, is that what you mean?

Hello,
Thank you for your reply.
It is not only a progress bar, but a new tab which indicates the evolution of the detailed task, the time remaining, the possibility of pausing it, ...

Ah, the Notifications widget, that is not the task bar in the Panel, it is an individual widget with a bell icon, you can just add this to the panel.

Thank you for the answer.
What is the name of this widget ?

it is called "Notifications widget"
