I liked it very much.
Multi device sync across platforms is awersome.
Bulk editing tried on 130+ pdf files by watermarking them with our brand name, it tool less than a minute to create it. Awesome.
Same tried for adding header footer in multiple files. Happened in less than a minute.
I hope this tool gets better and better and will be very useful down the line also.

p.s. I generally dont give five stars to any tools. But if there were 6 star option, i would have given this tool even 6 stars.
