I find PDF24 Editor brilliant at removing adverts and unwanted pages from magazines and making multi-langauage manuals into ones in just English. The previous version where wanted pages were dragged and dropped into place on a filmstrip was brilliant. Version 7.9.0 is fine if you want to delete just a few pages, but a pain having to un-check 400 pages if I only want to keep 20 pages from a pdf: can the next upgrade have a 'uncheck all' button please, or the option to use the old and new interface?
Also, I have found that using Version 7.9.0 a pdf of a magazine from which I have removed 30 pages will actually be larger than the original - I do not want to compress the file just remove unwanted pages....
