Customisable wlroots/sway bar
I welcome contributions of any kind with open arms. That said, please do stick to some basics:

- For code contributions:
  - Fix any `cargo clippy` warnings, using at least the default configuration.
  - Make sure your code is formatted using `cargo fmt`.
  - Keep any documentation up to date.
  - I won't enforce it, but preferably stick to [conventional commit]https://www.conventionalcommits.org/en/v1.0.0/ messages.


- For PRs:
  - Please open an issue or discussion beforehand. 
    I'll accept most contributions, but it's best to make sure you're not working on something that won't get accepted :)


- For issues:
  - Please provide as much information as you can - share your config, any logs, steps to reproduce...
