Hi Arek,
Thanks for providing valuable inputs. Connect for Mobile doesn't have in-built support for pdf viewer / 2D document viewer yet. Its part of our roadmap. We will keep you posted when this is made available.
If there are specific requests with respect to features(apart from markups), please let us know. Also could you please let us know your workflow on usage of pdfviewer in mobile. Is it part of on-site team and how frequently they would use this. This will help us a lot while prioritizing.
Regards
Darshan Kamat
