[feature request] configuration

[Mantas-2155X]

Hello, thank you for making this tool.

I do not see a way of configuring it without modifying the code itself, adding configuration via file or the TUI itself would be great.
Mainly changing the location where it places the downloaded .torrent files as I would rather have them not be in root of my home directory. Ability to change the keybinds would also be nice.
