Why is an app marked Caveat just because I used it recently?
Short answer: It's a heads-up: moving is safe, but you seem to use the app often, so you'd notice slower launches and need the drive connected. Big, occasionally used apps are better candidates.
It's a gentle heads-up, not a problem. Moving an app you used only days ago is safe, but you're likely to open it often, and launches from an external drive can feel a little slower — plus it only works while the drive is connected.
The best apps to move are big ones you open occasionally. See which apps to move.
