Make Ligatures OFF by default and have a checkbox in Preferences > Type
Please make it possible to turn off all ligatures within the Preferences > Type dialog box, then make it Off by Default.
Hate having to turn off ligatures every time I do a new packaging artwork - all my FI letters turning into a Glyph!

+1 I have been having trouble with certain fonts that have a glitch where the Ligatures option is disabled even though the font carries Ligature glyphs. Would like to have the default to be off for the ligatures also!
