I am not comfortable with the work flow of BrainBox. I suggest having two right click options (or left click options), one for Add to Brainbox and one for Select Parent thought. This allows the user to chose AT THE TIME OF ACTION, rather than having had to remember to set the setting on the last usage. I do not want Vulcan to open if possible, I would just want a search box, but understand if that can't happen. When using the Extension, I don't want to "be in The Brain", I want to be moving on to the next thing quickly.
