Nope, FingerPrintSwitcher is a service that serves fingerprints.
You can use that service in BAS to obtain desired fingerprints and
use them inside BAS for automation purposes.
FingerPrintManager is stand alone BAS aplication, that uses FingerPrintSwitcher
service just as any other COMPILED BAS program. It is created by @fox as I recall
around a year later after FingerPrintSwitcher service was introduced to BAS community.
So it is used for manage profiles MANUALLY, without need of using BAS itself, which is
meant for AUTOMATION purposes.
