Weinre in browsersim slow/not-informative

BrowerSim weinre seems to load very slowly and there is just a big white dialog shown while it do so.

I initially thought it was broken but after 4-5 attempts it suddenly showed up.

Problem is users has no idea what is actually going on.

Could we:

A) show a progress monitor (even a fake one would be useful)

B) show what url the dialog is visiting (that gives a hint it is waiting)

C) have a link/info button explaining you can configure weinre in preferences

Ca) have a dialog pop up on initial start of weinre explaining it will inject weinre and go to client url X which can be configured in the preferences...and then a "Do not ask me again" checkbox for future usage.
