Feature Request: Command Log

I have been using lazydocker for a bit at work alongside lazygit and I realized a key difference that helped me figure out the commands and keep them in my head, the command log at the bottom of the gui.

Here is [lazygit](https://github.com/jesseduffield/lazygit) where they have the command log at the bottom. I believe this is helpful for myself and others when lazydocker isn't available to use and it can help newbies, such as myself, truly understand and better utilize lazydocker.
