Hi,
well, what exactly are your problems? For the Background Remober for Example you can always refine the cutout when clicking on "customize" after selecting the image. It should also be clear that there are better suited Images for that task and others that are not so good for that.

For the Scheduler and the other issues you mentioned there are no details so we can not help you in Detail. Empty Layers can just be deleted so it's a little tidier.
For all other issues it would be good if you give more details on what we can help with. Hope that helps.
regards,
Henrik
