I don't know such an addon but I doubt anyone would like to create something like this as you cannot access or show info about skills or morphs ingame if you haven't unlocked them afaik. This would need you to keep an offline database of all the skills and data which needs to adopted each patch. No thanks... too much time to invest. ALT+tab is enough and quick imo
Possible helpers could be these addons:
Superstar
My build
Alpha Gear
