Cargo Features

wmfocus has no features set by default.

[dependencies]
wmfocus = { version = "1.5.0", features = ["i3"] }
i3 = i3ipc

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
