Well, we've also measured the time the right panel needs to load
(Network module in Firebug AFAIR, my colleague did those tests) and
there's a measurable difference. I don't have the numbers at hand, but
it was something like 0.9-1.5s vs. >=3.5s.

That's why I wrote we have the feeling as I didn't have exact test
results at hand. And I thought it's more polite than just writing: "Hey
it's slow like broken, how could this have been released that way?".
That wouldn't have helped I guess...

I never proposed to skip the loading mask at all. The only thing I said
was that there is an extension - and that the extension doesn't solve
the unerlying problem of the slowed down loading. If the right panel
(list view to be a bit more detailed) would load a bit faster, I could
happily live with the loading mask. (And if one could disable it if
he/she doesn't like that one that would be the prettiest solution)

I agree - it's not just the ExtJS stuff. But I cannot prove or solve
that since I have no deeper insight in the core-code. That's why I asked
- no fingerpointing at all. I hope you didn't get me wrong!

Cheers,
