I'm wondering if something like this has already been added, if not myself or someone else who has the time should try and add this functionality. If you've ever used a system such as Taiga, there's nice left and right navigation buttons to quickly go through issues, especially if you have a lot of them.

Currently with Github, every time you read an issue and comment / close it, you then have to go back to the entire list of issues, remember where you left off and somehow keep track of the next issue to open.

This lack of functionality has bothered me so much that I actually sent Github staff a long email about it over a year ago. They replied but since then have not added this basic functionality, for a reference this is precisely what I'm describing, if you've ever used Taiga they already have this.

As well, a similar type of functionality when you want to quickly go through commits, review changes, pull requests, etc. would also be extremely helpful.
