1. ability to create manual checkpoints, which then enables me to return to that specific spot in listing (by checkpointing a post or something), and view new sifts from that point on. Easier to navigate the unsifted area.

2. voting gives you added sift bonus (encourages voting).

3. Easier way to view Sift Talk? Maybe it's just me being used to default forum styles. I just can't get used to sift talk section with the content of the post being shown right below the title. It just confuses my eyes.

4. Making a separate Recommendation section? I didn't know where to put this.
