@Anahkiasen Congrats on finally moving the repo and plugins under one roof.
Does new version solve issues from this? https://github.com/rocketeers/rocketeer/issues/273

I discovered it lags for deploy:update, too.
Since most of the time I only change code, it sucks to wait for symlinking unchanged stuff.

Is it possible to make steps configurable? Like '--skip-symlinks', '--skip-composer', '--skip-migrations'.
