The Elive-E16 icon repo is 'public' now:
Albeit still a work in progress....So changes may be due.
Soon it will be available as an Elive .deb too.
Considering that there's 2 options to install icons:
- System wide in '/usr/share/icons/' ... where they'll need to be for 'cairo-dock' to find them through the GUI appearance tab.
- in '$HOME/.local/share/icons/' Where 'lxappearance' (in 'preferences ->Customize look and feel' menu) puts them when importing.
That is something to be reckoned with.
Feel free to use and report issues, wishes, ugly or missing icons.
