Scott Wilson commented on RAVE-831:
-----------------------------------

Thanks for this Olexiy, Can you create a corresponding issue in Wookie 
connected to this one, with the Wookie patch attached?

In response to Chris's comment - user testing indicates that awareness of IWC 
is a problem for users. 

This is particularly of concern where the use of some widgets has additional 
consequences, such as widgets that communicate with enterprise systems, that 
incur a cost through use (such as SMS) or that initiate sharing outside of the 
portal (such as FB & Twitter widgets). However there is also a general 
usability issue in that users often don't know when one widget has updated the 
content of another.

However, it should be up to the portal site owner whether to enable IWC 
highlighting.

> Evaluation has indicated that the inter widget communication going on in the 
> background is not noted by users. 
> One possible solution would be to flash the frame of the receiving widgets in 
> some color.
> Another option is to have some small icon flying from sender to receiver. The 
> latter one should only occur for user-triggered IWC, however due to possible 
> animation overload.
