### Release Notes

<details>
<summary>dlvhdr/diffnav (dlvhdr/diffnav)</summary>

### [`v0.4.0`](https://github.com/dlvhdr/diffnav/releases/tag/v0.4.0)

[Compare Source](dlvhdr/diffnav@v0.3.1...v0.4.0)

### Switch focus between panes, config file, mouse support and more!

This release is brought to you by [@&#8203;pablospe](https://github.com/pablospe) who made some serious improvements across the board!
Thank you [@&#8203;pablospe](https://github.com/pablospe), your work is really appreciated! <3

#### Focus Switching

You can now switch focus between the file tree and the diff by hitting <kbd>tab</kbd>.
This lets you use a wider set of movement keybinds like actually navigating one line at a time with <kbd>j/k</kbd>.

#### Config File

`diffnav` now has a config file (check the readme on how to set it up).
It lets you hide the footer/header, hide the file tree by default or set its width.

#### Mouse Support

You can now click the files in the tree or scroll the diff with your mouse!

Again, this was all done by [@&#8203;pablospe](https://github.com/pablospe) so give him some love!
