i am so curious about your use of colon to pluralize initialisms (which i've always found awkward to pluralize, especially in lower case). is that cultural? an intentional choice?
- guis
- gui’s
- gui:s
Top looks like French. Middle looks like like the gui is owning something. Third is clearly the right choice :)
- GUIs
Yes, ok, maybe that is correct, but why are you screaming?
On further thought this works similarly for US layout.
