Do you know how to play an F# chord without a capo? Can you play Cm7 in ten harmonious inversions? Yes, I said ten. Add Cmj13 in six inversions. All comfortable. All playable. All different. And substitutions.
A great full chordal inversion is relatively rare on guitar. You have just four fingers and six strings to work with. Most guitar chord inversions leave out one or two harmonic tones. But which tones?
What Jamorama says about their coursed is "We want to make that journey a little less daunting; a little more enjoyable; a little more accessible for anyone that’s ever struggled with learning something new.”
