Add a configuration file

[orhun]

Is your feature request related to a problem? Please describe.

Having a configuration file for managing the application settings would be good in the future. (It looks like it's going to be needed anyways.)

Describe the solution you'd like

Implement a configuration file parser using config or rust-ini crates. Update the config values in the application after parsing this file.

This would be great, especially also to define colorschemes using, for example, flavours.

Also, I'd just like to say thank you for creating this really cool TUI. I've been looking for something like this for ages. 😄

It should be also possible to change the file explorer utility (default: xplr) with using the config file.

The configuration file is implemented now. (See #configuration)

I dispersed the other mentioned issues to their separate issues: #31 #32

Closing.

Amazing, thank you!
