* everything is on fire

* silent trait check

* how did it even become CRLF

* minor formatting

* fix icon updating and adds silent insertion to global trait list

* adds the new parameter to documentation - whoops!

* pain

* contra review

* contra review again, reduces amount of checks for user in the loops
