I’ve been bugged by the autocompletion feature where whenever I type “:” it adds the “;” as well. It slows down my coding so I’d love to find out how to change it. Searched through forums and found out that I should go to preferences -> browse packages - but I have no clue what file to look in and what part to edit out/disable.

Which language/syntax are you talking about? I assume something CSS-like.

I can not reproduce this problem with the default CSS configuration, so it’s most likely caused by a package you installed.
