I journal using DT. In DT Pro Office there is a handy icon associated with the journal template - a pen on a yellow background. This is a helpful icon as I can easily pick out my journal entries amidst other notes.
The same icon is available for the journal template in DT3, however, once I start typing it changes the icon to an RTF thumbnail. I’ve had a look at the settings and made them exactly the same as DT Pro Office. However, DT3 continues to change them automatically.
