Wake-On-Lan (WOL)

I find it pretty frustrating. I try adding a client to use it on, and get it to save. Finally succeeded. Then I click on Add, and it overwrites the first one. Not the least bit intuitive.

It works, in that it does send a WOL packet and the remote computer does wake up. However, the UI is not intuitive at all - it's basically impossible to use. I haven't been able to add more than one MAC address without it overwriting the other one. Until this is fixed I won't use it. Ideally, in future, I suggest that you show buttons for each computer that is added. That way you just point and click, without selecting from a drop down list. There are plenty of command-line and app alternatives for WOL, but I did like the idea of it as a Chrome app. Pity.

Is there no way to save?

It just works with IP 255.255.255.255 and your MAC address, port 9 in most cases. Probably nothing in SecureOn.
