Somehow the font in the editor has been changed. It’s truly horrible now. 
Unfortunately, I can’t find an option to change it (only the font size): did I miss something, can anyone help me out?
Beyond that: the tools bar is the horror, I can’t get rid of it. Does anyone know how to un-pin it? The pinned version is useless to me because the moment my mouse pointer hoovers over it the pointer changes into something that simply isn’t able to select anything.
These layout changes tend to make things worse.
