Code review comment for lp:~makyo/juju-gui/add-rel-improvements

Hi Matt. This looks like it will be a step in a good direction. I just went for a cruise around the UX for a second before I looked at the code, and I saw a few things that you might want to address, or at least run past Jovan, before a more thorough review.

 - the two experiences of starting from long-click and starting from the service menu are different in ways that surprise me, and in at least one case seems like at error. In general I prefer the long-click behavior.
   * lines started from the service menu can go crazy when you hover over things that are not a target service. For example, try hovering over a relationship name. For me, the line then goes from the service start point to [0, 0]. I see other similar issues that I won't clarify now, but if you can't dupe I'll be happy to provide more details and screenshots. (This does not happen with long-click.)
   * lines started from the service menu cannot go over the service, unlike the change you made for long-click. I think they ought to be the same.

Also, unrelatedly but concerningly, I discovered bug 1072433. That looks pretty critical, but it is in the trunk. I put that in the kanban board.

I'm going to stop the review for now until I hear back from you on how you want to handle my UX observations.

Thanks,

Gary
