Next/Previous commit navigation
### Proposal
Add a way to make moving between commits easier. I'm sorry if this already been proposes (rejected), I did search for for a similar feature.
Current way:
1. open a file.
2. Click history.
3. Click specific Commit or click `Browse Files`.
4. Click `View file at` .
Easiest way would be to add arrows or timeline from graph itself to the top of the file. I included two screenshots.
**Arrows below the commit SHA.**

**Timeline copied from the graph page, where each dot would be a commit. Clicking on each would move the timeline, keeping the current commit dot in the middle.**
