This settings offers the tiny jokes and some more lightened text items when using the phabricator, while this is fun if you know what does what, this can be straight forward to use. But, to new contributor this can be totally confusing.. For instance it is very hard to decipher "Set sail for adventure" button when commenting on tasks.
With regards to our goal for onboarding it is very important that we provide not-so confusing user interface to new contributors.
If there is agreement in general about this, I can perform this modification.
