following some functional tests on the feature I add below some improvement proposals for this same PR, they are simple changes but they should improve the overall UX,

• Proposal 1 about MS
• Proposal 2 about GNODE-CLIENT

Proposal 1

MS identify panel for Documents:

These two fields are available among the returned metadata to display additional, more useful information in the Identify panel.
These could be used at the top of the Identify panel above the metadata.

In particular, this feature seems indispensable at the moment, otherwise the user will not be able to view PDF or similar documents in any way, the right side panel is too narrow for any content

Proposal 2

In subsequent interactions when adding new documents, it's not immediately clear where and how many documents have been imported, and in which new layers in the TOC. This situation occurs with two layers with the same name:

Additional visual feedback may probably be needed just for the legend of layers that group documents like this one. There are two options: one is to display the number of documents linked to the newly created layer, like this:

An alternative is to adjust the title of the new layer created for the document. This way, the newly created layer can be differentiated from the previous ones just created in TOC:
