xfce4-terminal
Chromium
I’ll look into these, see what we can do 
XFCE4-term should be installed by default. So i’ll check that.
WiFi - I’ve installed network-manager via apt-get -
Its worth noting, DietPi has a lightweight program to setup your WiFi adapters. Simply run dietpi-config from the terminal, or under system menu. Then enter the Networking options menu.
As you now have Network-Manager installed, probably best to stick with that
I’ve noticed that /boot/uEnv.txt is getting overwritten at every boot… I just tried hard-coding MAC address in there - doesn’t stay…
DietPi creates a RAMdisk during boot for common files. You’ll need to edit it from /DietPi/uEnv.txt.
I kinda HATE using the Pine64 forum - one of their admins is whiny namby-pamby little prima-donna - always butting in to conversations with the wrong information
Yep, know the feeling.
I tend to ignore those forums and just get on with working on DietPi. Its like a childish pissing contest to see who has the biggest ego and knowledge.
The funny thing is, most of the time they dont like sharing their knowledge (if it exists), instead, resulting in childish “your wrong”, “Don’t do it that way” with no reason why or even a method for the “best/correct way”. So kind of useless and pointless lol.
Saying that, even I get things wrong sometimes
