sounds great on paper until they still remove moves because of job changes or just flat out balancing and some moves growing out of date in SE's eyes. Also new moves in some aspects would naturally phase out some older ones depending on how the design team comes up with em. Point being making them a single button would not stop them from removing skills. There's more to it then just space. The bigger issue is balance and flat out job changes overall.
