Is there any way to display an independent variable which itself is not a part of any tvb in the protocol tree?

Look in doc/README.developer for the functions that start with proto_tree_add_ other than proto_tree_add_item(). If you don't need it to be filterable, you can use proto_tree_add_text() to add any text you wish.

It's also good practice to mark the variable as "generated" (meaning: not from the TVB) using PROTO_ITEM_SET_GENERATED()
