As the agent is generally used for "here I'll send you think open it so I can connect" type situations, it would be nice to be able to customise the icon for the program along with the rest of the customisations.
I know there's other programs out there which can do this after the fact, but it'd be nice not to have to mess around with those.
Unfortunately, we do not provide white labeling of the icon. Apart from purely marketing reasons, there is another reason - the program should be clearly identifiable by the user (and security staff/admins if any) as being Remote Utilities.
However, you can still customize the Agent window itself, as described in this tutorial.
