How do I show all open fonts?
You can do a Find to see what fonts are open:
Use CMD-F or go to Edit -> Find Fonts to open the Find dialog
Change the first field to ‘Activation’ and the second to ‘Activated’
The results will show you all fonts that are active in Suitcase Fusion.
You can save this Find as a Smart Set by clicking on the floppy disk icon in the upper right corner of the Find dialog. A new set named ‘Untitled Smart Set’ will appear under your font library. You can name it ‘Active Fonts’ or whatever works best for you.
