One issue I am having with this is the random dialog box that appears and doesnt go away.
It also gets slow after a while

lots of addresses. Also, something I would like to see if a way to clump together verified owners / addresses in one grouping to really be able to see what belongs where.
Yep I noticed that problem with the dialog box that doesn't go away - I'm addressing that issue along with a laundry list of other ones in two days or so. The slowness is definitely a result of too many nodes being drawn - not too sure at the moment how to get around that.
I wanted to ask you - what do you mean by clumping together owners? Right now, owners already represent groups of addresses that all belong to the same entity. What do you mean exactly?
