In the Preferences window, you will be able to :
- modify colors that are displayed in the Matrix,


- enable or diable a plugin,


- configure a MAC address, two IP Addresses and the TTL value of Ethergrouik.


- modify some graphic features.


Could you tell me more about the network management : what is it for ?

If Ethergrouik has to send bytes through the network, it will have to use its own MAC and IP (the 1st one) addresses.
Concerning the second IP address, it only answers to ARP Request. Why ? It does so to save time if I feel like connecting my computer instead of a router ;-)

What about tools : we can see them in tabs, but there is no explanation ?
Well, please be patient and wait a few days for more information because it is not finished yet. Tks.
