Feedback? Okies - as I said it's an excellent idea, and it works. I upgraded to the last version (23 effects) . . . and they all work too. The only trade-off I've found - and sadly it's a big one - is the adverse effect on page loading times.
Once the transition kicks in, the effect (and durations) display correctly. The problem is with the delay before anything happens. With the hack disabled, the load times return to normal. I have reset the durations, but it doesn't help with the actual loading time, this only reduces the transition time.
For now, it's still installed, but I've had to turn it off in favour of acceptable load times. There are always faster servers (and faster computers) "just around the corner" so I'm hanging on to this in the hope I can put it to use in the future. If Ziki or anyone else has any thoughts on improving the speed, I'd love to turn it on again
