Now it's working great! Nice widget! I'll update the import process to make it easier to import specific items into specific menus because this is currently a bit hard to do.
In general when right-clicking a file in a floating menu it should get the . bttfloatingmenuitems extension, not sure why it didn't do that for you. With that extension it will import into the currently open menu:
