Q Light Controller+

When updating a Chaser sequence that has 100+ steps, the "Common Hold" time update takes a very long time. One of my chasers has 830 steps and it takes about 3 minutes to update the "Common Hold". During this time the program is unresponsive.

I've noticed this too on a 300+ steps chaser.
Probably I've added too many sanity check on copy/paste.
Will look into this
