Can math preview support multiprocessing?

[note286]

The math preview is very easy to use. Thanks to the developer. I turned on all the math to automatically display, which is great. I found that the same math should be cached, not repeated rendering, and reduce CPU operation. This is a good acceleration method, but I found that the math are also rendered one by one. Some of my tex files have many math equations. The first time rendering will take a long time to complete, so supporting multiprocessing rendering is possible? You can add a switch in the settings. If the computer has more cores, users can start multiprocessing, otherwise users can close it.
