Thanks for that catch! I totally forgot that I hide menu on link click. I have already fixed that and now when you click on link menu only hides on mobiles and tablets; on desktops is always visible.
The right frame isnβt cut off on the left side, but itβs behind the menu. I did that because I think that on small devices list of all list items is more important than content (less scrolling to find interesting material).
EDIT: I decided to hide the menu on mobile and tablets by default. On desktops is always open.
