There are quite a number of configuration options in JBackpack. You can manage these configuration options by using so-called profiles, files that bundle all these configuration options. If you open the menu, there are several menu items for working with profiles:
You can
create a new profile (this resets all configuration options to their default value)
open saved profiles
open recently used profiles
save profiles
Working with profiles makes it easy to copy the JBackpack configuration from one machine to another and makes it possible to try something out without the risk to lose a usable configuration.
