Miscellaneous is the fourth section of the Settings mainpage.
It's very short with just two buttons:
The first button opens the Sailor Logbook Homepage. Here you'll find a link to the Sailor Logbook S App manual (this manual). The homepage can also accessed by entering the address in a browser.
This button works just like the link in the grey box inside the Comments textfield, as shown in Main elements of the Track mainpage.
Feel free to tap the second button and write a review!
