I worked on piano chord inversions. I noticed that if neighbouring chords share a note it’s better to keep that note for both chords and use an inversion to keep the chords close together positionally on the keyboard. A good example of this is the I to V: C E G to G B D, you keep the G note and play a V6; this means that the chords will remain close together and you only need to change 2 notes. I spent some time going through some simple chord progressions and seeing if they had similar notes and how best to keep them.
