Quick tour - Queue

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.

The checkbox "When idle, work on other projects" could give the computer something to do while otherwise waiting for you. However, once it started a command it will finish it. Thus when you are interactive with ZTX37, refining prompts, you want this off.
