Wierd behaviour when renaming objects from settings menu

[sqpdln]

Maybe this is expected behaviour, but I find it wierd, and I messed up several objects before I noticed it.

1. Create a new visualization and save it as something, like "moscow".
2. Rename the title under settings > objects > visualizations > moscow, to something else, like "discow"
3. Go back to visualizations tab and open "discow". This now still resides under url /edit/moscow?_g...
4. Save it in the visualizations editor as "discow". This will create a new object with a new url, /edit/discow?_g...
5. In Settings > objects > visualizations we now have two objects "discow", but with different urls.
6. Create a third object and save it as "moscow". There will now be a prompt asking if you want to replace the object. At this point you have no idea what you're actually replacing.

I figure the url uses some kind of object ID, which also is used in the dashboards.

But I think the expected behaviour would be that the ID is renamed aswell, to avoid this kind of confusion.
