Feature Request

[thx4ever]

Hi, i'm enjoying this software so far, but i need if this possible to add option to control the queue, like only start new queue when the first are done, because it affects cpu usage like 50% of cpu usage with aomenc_keyframes and only have 50% more cpu to encoding process, my cpu are Intel E5 2678 V3 with 12 core with 24 threads.
Thanks
