Instead of re-printing the whole screen every time the arrow moves in the app list, you could use the LOCATE command. So, when you pressed down, it would just replace where the arrow was last by blank space (example: LOCATE 6,18 PRINT "") and place the arrow (example: LOCATE 5,17 PRINT "-"). And, of course, you would change program sections just like before, so when someone pressed A, it would launch that app.
