You can clone with
HTTPS or Subversion.
The plugin shows files of last project when you close a project and open a new diferent project
1. Open project A
2. Use off (it loads files first) and you can search
3. Close project A
4. Open project B
5. Use off (it does not show loading) and the files it shows are from last project.
What NB version do you have? And what operating system?
The off is 1.0
Anyway, congrats for this plugin. I'm much glad with it.
same problem here with NB 7.0 and OFF 1.0.1
