after watching the video, it seems you create a sort of capo with your index finger, neat

I'm really focusing on learning the major/minor/7th chords and playing them quickly through the common I-IV-V7 progression, on various keys; every bit of info and practice is good for me

Yup, that's exactly it, your index finger is a moveable capo and you use your other fingers to play the A, Am, E and Em shapes. Now the really cool thing is that playing 7ths is really easy with barres, you just have to do less. Examples:

Barre G = [3 5 5 4 3 3]
Barre G7 = [3 5 3 4 3 3] (just lift the pinky)
Barre Gm = [3 5 5 3 3 3]
Barre Gm7 = [3 5 3 3 3 3]

Barre C = [x 3 5 5 5 3]
Barre C7 = [x 3 5 3 5 3]
Barre Cm = [x 3 5 5 4 3]
Barre Cm7 = [x 3 5 3 4 3]
Barre Cmaj7 = [x 3 5 4 5 3]

And since you can just move them up and down you can play all major, minor, dominant 7th, m7 & maj7 chords with this stuff. So a basic blues in G would be:

G [3 5 5 4 3 3]
C [x 3 5 5 5 3] (notice how the hand stays in the same position and you can let the barre finger in place!)
D7 [x 5 7 5 7 5]

Now the same stuff in A (G->G#->A, A is two semitones or two frets above G):
A [5 7 7 6 5 5]
D [x 5 5 7 7 5]
E7 [x 7 9 7 9 7]
