TX37 has a queue where commands you gave to generate images are waiting. Your PC will process them one by one. Once processed, the command will be removed from the queue and marked as ready.
You can browse through the queue and remove commands you no longer wish to execute. Perhaps you obtained the desired result from a similar command or changed your mind. A canceled command will also be moved to ready, marked as canceled, without generated images. From there, you could restart it, possibly in an edited version.
You can choose the processing order for executing commands. FIFO (First In, First Out) is often logical, but LIFO (Last In, First Out) can also have its merits when fine-tuning your work. Or, let them be executed in a random order to boost creativity.
You might consider the checkbox "When idle, work on other projects" a no-brainer. Of course, you want that. But do you? When you are actively constructing commands, it might be better if the computer waits for you when idle, ensuring there's nothing from another project to finish the moment you give an order.
