[Lens] [Visualize] edit panel title and description from within editor

[drewdaemon]

Could we provide a way to edit the dashboard panel title from within the visualization editors (no matter if they're by-ref or by-val)?

We sort of get at this in the "save as" flow for library visualizations in Lens, though it creates a new panel.

Consider also a way to edit the description:

We want to be able to better describe the visualization and how to read it to the user. In some custom visualizations in Observability we've relied on providing a small icon tooltip by the title to present this to the user.

The use-case have now is for the Hosts Observability view where we'll have a number of metrics charts using the LensEmbeddable and therefore we're adding this feature request / enhancement.

Example of icon tooltip by the title

Something I've been thinking about this:

Right now, by value panels don't show their titles anywhere when you open Lens. The breadcrumb looks like:

When it could show the title, if the panel has one:

Additionally - what if the breadcrumb itself allowed for renaming? Google docs does this well:

I wonder what's stopping us from doing something like this. It could work really well for Dashboards too, because I know renaming dashboards can be an absolute pain. @andreadelrio
