How to remember the position in the VKontakte Feed?

Question

In contact with

Hello. Sometimes there is a good blog only in VK, I want to read the entire Feed from new to old posts.
Question: But how to fix the place where you finished reading? To enter the link and continue reading down.
Bonus questions :)
Is there a client for VK that cuts ads, unnecessary people and posts, allowing you to customize the Feed for yourself? I understand that the business of FB and VK is to influence the reader in their direction, so I want to minimize this influence at any cost.
I want to keep messages for myself (suddenly the Tape will be banned), mark them with tags, and that's it.
