Describe the bug
Not really bugs, just small improvements:

• iterating over set(tools) for tool in set(tools): instead of for tool in tools: to avoid unecessary overwriting iterations. The same for notebooks for-loop.
• remove physics=False leaving the default True for all regular tool nodes. This was set to False causing undesired freezing movement for two of the tool nodes.
• change the string title for the edges that shows up when hovering with the cursor. Instead of the "action" string now will show the shorter and more informative "notebook_url" string.

Expected behavior
More efective workflow skipping overwriting and all tool nodes having correct physics settings for free movement. Better edge info.
