Sorry I wasn’t clear. I didn’t mean the start of session.
What I meant is that I’d like to have the text start fading only in the last 5 seconds before the text is deleted (as set in “Dangerzone seconds”). Currently, the text starts fading immediately, which makes it harder to read. (Especially with a color background, which is another of your terrific touches!)
A 5-second “fade zone” before delete seems about right. Of course, if someone set the “Dangerzone seconds” to 5 seconds or less, then the fading should start immediately.
The added advantage of this is that the degree of fading would always occur at a consistent pace.
Personally, if you were to implement this, I would probably set “Dangerzone seconds” to 8, which would allow me to pause typing for up to 3 seconds without the text starting to fade. After that, the fading text is usually enough to kick me back into gear, but I’d always know that there is also another 5 seconds of fuse left on the delete-bomb.
