preferences? setting defaults?

Can you let us choose a default folder to start our search in?
Right now i'm mainly searching the folder that contains all the tenserflow models. So I have to use 'other' every time to focus on that folder, or I get a lot of unwanted results.

i'm using 1.4.2 I don't see any preference to change the default on anything that was mentioned in https://answers.launchpad.net/catfish-search/+question/229812.

How do you get to preferences?
