As a Roblox developer, it is currently difficult to reference a part in the Workspace directly from the Command Line.
It would be nice if there was a way to click and drag a part into the Command Line (similar to how cmd prompts work on most major operating systems), or a way to copy the fullname of a part directly from the Explorer.
This would solve the issue by streamlining the process, and making the studio environment significantly easier to utilize.
What are you trying to with the the Part in the Command Line?
For instance I often CFrame Parts from the Command Line. To do this I click on the Part, then have a CFrame line of code in the Command line to perform on that Part. After selecting the Part I click in that Command Bar line of code and hit Enter.
If you have a Part selected in the Viewport with the Select, Move, Scale or Rotate tool as I said, and then just run the code in the Command Line by clicking Enter.
You can also just click on the Part in the Explorer window.
This is the line of code I juse to CFrame Parts individually on their own axes, or you can select a bunch of Parts and do the same thing as long as they are aligned in the same Orientation:
