Need more features

Update 10/08:
Done , sadly i ditched dscloud in favor to readdle Documents app, until I get below feature in DScloud. Im construction project manager and sharing documents is a must in my job. To manage PDF Ive create a folder shared between Documents , PDF expert and bluebeam revu. Then I can work in all way I need with PDF. But for sure have all in one apps such DScloud will be so much more ergonomic

Please here some must have features :
- PDF editor : insert, delete, rotate page , merge PDF
- Zip files : compress / uncompress ( Documents app from readdle do it )
- Share : send multiple files in one mail ( Documents app from readdle do it )

Please as usual , I know synology is listening theirs customers

Thanks
