Just floating an idea out....

What if the trigger icon was used only for psychological triggers, and for physical triggers (such as graphics that cause seizures) the word "trigger" can be used.

That not only solves the problem that annie mentions (not being able to use or see the trigger icon when the graphics are turned off), but it also would allow for people to be able to tell the difference between an emotional trigger and a seizure trigger.

Just an idea - feedback is welcome
