A quick tip on setting the Text Tool in OmniGraffle to your favourite font.
I have my preferred font when creating diagrams and you set effectively make it the default font. There are two ways that involve the way you choose the Text Tool.
One ‘trick’ is to press click and hold on the Text Tool and the following menu will fly out. This is recently used list of fonts – select on of these and it become the default for any next Text blocks you create.
The second option is ⌥ click on the Text Tool and select the Inspect Style and then use the Font Tool that opens to select your font.
