I'm using shared modules, and they show up like this:
When I open it, the tab looks like this:
which is the "non-shared" icon.
(As a small bonus, perhaps the "linkarrow" could be improved a little, to make it more visible. Perhaps by doing something simple, like making the "linkarrow" have a yellow background, to make it stand out a bit more?)
There is a new modules tree component coming. In the new version you can link modules from any folder you like and it shows the path for linked modules:
Linked modules path can be relative or absolute.
The "shared icon" is removed. The shared feature is still supported but the new feature is much more powerful.
