Panel icon/buttons customization

[ManPython]

Problem

Sometimes icons are bad configured on panel, as next line with something important

Proposed Solution

I think it bee good to turn on option to manage icons like in Firefox customization

Additional context

Related: #13869, adding context menu options for toolbar customization.

Of note, it is already possible to customize toolbars in JupyterLab albeit a friendly UI is missing. For more, see the documentation.

I think is difference around Lab and pure Nootebok? Coz all icons that we see on Nootebok are not available on jupyterlab (why?).

They are two different softwares that have nothing in common on the frontend side. Therefore extensions for notebook does not apply in JupyterLab and vice-versa.

[ManPython]

But there is vision to have both or not?
Eg. some extensions can work by both side, other maybe not.. coz some GUI, etc.
Anyway.. right now I see that some from notebook can work in lab, but are not here.. it's need to analysis I think as project directions.

The future major version notebook v7 will be built on top of JupyterLab packages v4 (+ customization). The extension system will be identical. But extensions may not work directly; for example notebook is document oriented that may lack some panels available in JupyterLab.

Extensions for current and previous notebook versions will not work in v7.
