At the moment it is pretty much impossible to easily refactor tags, UDTs, Views, components' names and scripts without messing up the project integrity. This is a feature which is a must in a modern IDE and it is necessary to avoid to break all the project's references when simply renaming one of the aforementioned items.

Moreover, I suppose the search feature should be improved as well, adding a way to show all the cross-references connected to the selected item, similarly to what we already have in programming tools such as TIA Portal from Siemens.
