stop loading resources in "network activity"
 

i remember, that it was possible to stop loading a single resource in "network activity" in earlier versions of omniweb.
this was a nice feature. especially helpfull, wenn just one resource (for example an image from a third party site) won't load and prevents the whole page of loading.
now when i stop such resource, the page won't go on loading.

maybe there is a way to re-implement this?
