The idea is to add a feature that will allow users (more useful in development time), to activate a ui path text within components / screens / Blocks. This way it is easier for a developer to track what screen he is seeing. and navigate through the module / ui flow / screen or webblock.
For a first approach I see that at the webblock level it is ok, further it could be until the widget level.
The logic is to allow this feature to be activated in a user's browser, this way it is independent who is seeing the feature and who is not.
For new arrived persons to an on going project is a easier way to check what they are seeing.
