I like it on Win XP that its easy for the user to observe (unexpected?) network traffic on a very basic level by looking at the systray netshell icon.
It is flashing when network traffic occurs.
Ros also currently offers this feature, but the contrast between flashing and not-flashing is so low, that I currently have to move my face 1cm before the monitor to see the difference.
This icon-set aims to enhance that contrast to make network activity easier visible.
demo from GonzoMD (thanks again for pointing me to right icons)
and one by myself which gives even more contrast
I'd go for (myProposal).
What do you think?
