Congratulations Barry .. I used to be a puppy user years ago .. now a LinuxMint (LM) user but decided to see what you were up to and discovered easyOS 3.4.7. Very innovative with the containers tech. Had some exposure to firejail-firefox on LM. Glad to see mpv as an included app. I decided to write the 3.4.7 img file to a usb attached M.2 sata drive to be used as the only boot drive on an old 2008 intel mothballed E6300 core duo BIOS system w/o secure boot. Are you planning on supporting secure boot for easyOS?.
On LM the Network Manager Applet allows importing of openvpn config scripts that my VPN provider supplies.. works very nice. Using the easyOS version I get a msg that it is missing a plugin to configure VPN connections. Any chance you could provide VPN connection type that imports a saved VPN configuration - file type .ovpn?
Thx again for your efforts..
