[kepler-dev] Icons in the *DataSource actors

Before I make a recommendation I'd like to understand what "states" these
icons have to display?

And it does seem a bit unusual to me to have processes doing something when
the user hasn't instructed the workflow to execute.  But I'm not familiar
with these specific actors or the specific workflow you are referencing.

Is it some kind of polling thing?

On a general note, I pretty much agree with Matthew's suggestion of having
the icons fit in with the general scheme then doing something else to
indicate state changes (highlighting, superimposing, putting some symbol
above or below that indicates state change etc.)  There are a variety of
ways we might do this.

Kevin -

I'd noticed (and ignored ;-) the eml200datasource actor; I agree with 
you that it's not visually compatible with the new icon scheme, and had 
meant to discuss it with Laura.

I'm wondering if a better way to do this would be to use an assigned 
icon that doesn't change, but then the actor superimpose something on 
top of it that gives the user some feedback on status/progress (instead 
of switching out the entire icon or changing its color).

This way, the background icon would always "fit" with the color scheme, 
and if the icons change in future, we probably won't need to change 
anything specifically for these actors, since they are superimposing 
their "status message" on top of the icon.

Laura - do you have any comments?
