Small improvement here. With a part placed from Content Center and saved as a Standard part you can right click on it and select to change size. This will change the size of the part and update the size change in the Model Browser. If the Content Center part was created as a Custom Part then the browser will not update and will reflect the old size if you edit the part.
I would like the browser to always update and reflect the proper name after the change.
Insert flat bar 1/4x3/8 12" long
Part name displayed correctly in the tree.
RH click and select change size.
Select 1/4x1 long and notice that the file name will change.
Now doing this again with a pices of 1/2 flat bar, but inserting it as a custom part the model tree will not update.
