This isn't a huge deal as it doesn't technically break anything, but I noticed that if I'm in Fiddle A and open one of Fiddle A's mock data items (which creates a tab in the toolbar at the bottom), the mock data tab from Fiddle A will remain open and active even when I switch to Fiddle B or Fiddle C.

As I mentioned, it doesn't technically hurt anything, but is a tad confusing.

For an example, start here ( and open the "loadtags" data tab.

Then switch here ( - the "loadtags" data tab remains open.
