I don't know of anyway to add a shortcut to your home screen, however, the next best solution is as follows. In ES enable tabs by pressing the menu key and press "Show Tabs". This will enable 3 tabs at the top of the screen, i.e. Local, LAN and FTP. click on LAN followed by menu key, followed by +new; then press scan and your device should list all IP adresses/devices it finds on your wireless network. Once ES has fouind all devices simply press and hold an IP address of your choice and press rename from the pop-up menu - that is if you prefer names rather than IP numbers. I'd recommend also to assign or reserve permanent IP addresses for known devices on your network through your router, otherwise, if your router assigns new IP addresses you have to go through the "scan" prcoedure each time the router changes them (assuming your router is the DHCP server on your network). After that all is very simple, open ES press LAN tab and click on the devices you have assigned previously. Job done.
