Bugs, combined with paywall, limit functionality

I need to convert multiple photos to a single PDF file, arranged in a particular order. However, this is rendered impossible because, when trying to combine multiple PDF files into a single PDF, a bug causes all files options to be displayed on top of each other in the screen to choose the arrangement of the files. On top of this, in order to re-arrange the order of the pages, you must upgrade to the pro version, which costs $4. On top of that, the process of converting photos to PDF files is rendered extremely tedious, as one must convert each file individually, and be prompted in whether to view the converted photo for every photo. A feature to convert several photos at once is sorely needed.
