Suidobashi: Underlined main navigation and Journal title

Dear Elma-Team,

Fantastic WordPress themes, especially Suidobashi. I have two questions for the Suidobashi theme:

1. Is it possible to make the main navigational items permanently underlined when a user is on the respective pages to keep the user aware that they are on the right page? Meaning, I am on the page “Journal” and the nav word “Journal” stays underlined, etc.?

2. Is it possible to add a title to the Journal page (e.g. “Welcome to the Journal”) that will stay at the top and that is not controlled by an entry?

Many thanks,
