Ok, what I'm actually doing is the following:
I'm a software developer and we have several different branches which are in different directories. Sometimes I have to switch between the branches quite often, but most of the time I am working on a branch for several hours or days.
For this, I have added aliases that let me built project files with FARR. I only want to build from the branch that I'm currently working in - to make switching easy, I now have aliases that change the search folder to the branch I'm working on.
Really cool now, don't have to go into the options dialog all the time.
