Very good with one smalle glitch Rated 4 out of 5 stars
Thanks, this is really a very nice extension and I'm pleased you even have one for IE (the wife uses it mostly).
One small counter-intuitive issue - and a difference to your IE plugin - is that Ctrl is pre-selected at the preview tab, and it is by no means clear what the Ctrl does. I thought it means you could force the preview eye to appear if you didn't want to wait for the ms specified. For a moment there I thought it simply didn't work because the IE plugin just immediately worked without having to *know* that Ctrl had to be pressed also.
Anyway, sorry for the long description of this issue. It should take away the fact that this is a VERY neat little thing :)
