[Request] Option to do not auto expand selected folder in the left pane

[Diogo-Rossi]

I mentioned this in #50, and decided to start a new issue from that.

The thing is: the application always auto expands selected folder in the left pane.

It would be good to have an option to not execute this behavior.

Example of the current behavior:

In the image below, when I select the "0" foder in the left pane, the app shows its content on the right, which is OK:

However, when I enter in the foder "Distros" (as an example) on the right pane, it expands the "0" folder on the left pane with its content, which I would like to not happen:

I would like to keep the left pane not expanded in this case, because in the current situation, it will make me to press a lot of down arrow keys to get the original state.

Is it possible to add an option for that?
