If I create a LTI tool using the external tools part of the administration workspace (doesn't need to actually launch):
Tool Title: Example
Button Title: Example
Launch URL: http://example.com
Then this tool should be available to be added to normal sites in Sakai through the Edit Tools menu in Worksite Setup, when editing a site.
If the tool is then added to a site using Worksite Setup.
Then another site is location using Worksite Setup again and when viewing a different site and clicking on the Edit Tools menu the LTI tool is pre-ticked even though it hasn't been added to this site.
