BREAKING CHANGE: mode keybindings dropped in favor of a global table **What this means in practice:** ```toml [keybindings.Channel] quit = ["esc", "ctrl-c"] # ... [keybindings.RemoteControl] quit = ["esc", "ctrl-c"] # ... [keybindings.SendToChannel] quit = ["esc", "ctrl-c"] # ... ``` are being replaced with ```toml [keybindings] quit = ["esc", "ctrl-c"] # ... ``` Mode keybindings were I believe a premature optimization which only brought additional complexity and redundancy to the code and did not provide any real functionality in the current state of things for end users.
