Some comments have already covered the subcommands thing, but why are you using the XDG_CONFIG_HOME directory `~/.config/wrm` to store files? This should be for _configuration_ not _state_. You should follow the specification for XDG base directories for this [1] which would suggest you put the trash in `~/.local/share/wrm/trash`
