Web clipper is now available on v.0.39.0 and you can download the chrome extension here.
While you cannot quick share from pdf to Anytype, if you manage to use chrome to open pdf, you can use web clipper to simulate something like that. It will be quite cumbersome though. Maybe support the file annotation feature request to have better workflow and perhaps OCR.
Canvas: See this feature request. It is currently tagged as improbable but it might come to live again with enough support 
. Until then, you can embed a Miro block into Anytype.
Graph view on mobile is an acknowledged request. According to team, it is likely to be a simplified version. For now, use backlinks/links to or links to access linked/related objects. (You can favourite these relations at templates for easier access, if they are not pinned to top)
Hope Anytype will continue to draw your interests even if it is not fully what you expected yet. Anytype is surely a growing application 
P.S. I don’t use table enough to give you any suggestions, but if you have any ideas on improvements, make features or join in current discussions on the forum, e.g. table, database, spreadsheet discussion
