Nice to hear. I'm kind new around, but it's great to have more feedback :)

Laslo's territory.

This should indeed be fixed for the next release. Haven't confirmed it myself (@ CCNA), but I'll try when I get home.

I have some ideas for the next release, concerning the effect settings dialog. I was thinking about allowing extensions to modify the dialog for an individual effect, so people can customize them.

About a widget for typing the value, I'll try replacing the rightmost label with said widget. That way, we don't lose the visual aspect we have now but we supply that functionality.

I agree with this. I've been confused with this issue myself :)

Hmm, maybe add that magic wand icon to the left upper corner of the event?
