there should be an option to export all the generated images in a single pdf, with the selected pattern, in sequence. it's currently does not have the option to export this way, instead it exports a pdf of each individual image, like 100 pages, = 100 pdfs. so this is not a good thing, there should be an option to "export all selected" or "each page as pdf" individually. so that's it!

Btw, I'm also a UX/UI designer with developement expertise. so looking for better career opportunities! ;)
