>          Issue Type: Improvement
>          Components: Core UI
>            Reporter: Pierre Villard

> Consider a RouteOnAttribute processor with "Route to Property name" with many 
> dynamic properties. This will lead to many relationships (r1, r2, r3, etc). 
> Now consider an UpdateAttribute processor.
> Connect RouteOnAttribute to this UpdateAttribute processor and select r1 and 
> r3.
> If the two processors are stopped, opening the configuration of the 
> connection will show an alphabetically sorted list of the ALL the 
> relationships (of the RouteOnAttribute processor) with checkboxes and r1/r3 
> will show as checked.
> Now, if one of the two processors is started, opening the configuration of 
> the connection will show an alphabetically sorted list of the ALL the 
> relationships (of the RouteOnAttribute processor) and the only distinction 
> will be that r1 and r3 will be in bold.
> When having many connections (think 50+), just showing the selected 
> relationships in bold is not super user friendly. It's really hard to 
> distinguish the bold names in a very long list of names.
> When one of the processors is running and we're just showing the details of 
> the connection without the option to change the list of selected 
> relationships for that connection, I suggest that we only display the list of 
> the selected relationships.
> For reference, the related code is here:
