Build me a clean Windows app called Thumbnail Maker Lab that helps people make professional thumbnails and image layouts without a bunch of clutter.

I want a simple editor where I can create designs with text, shapes, and vector style drawing tools, then export high quality print ready images. It should also have a few smart AI style helpers like auto selection, content aware fill, and upscaling for fixing images quickly. Please make batch processing too, so I can apply the same preset to lots of images at once.

Keep the interface easy to use, polished, and focused on speed. It should feel lightweight and practical, not like a bloated pro suite. Use a modern desktop look, and if you need to check current docs or best practices online, go ahead.
