Include Pastebin Widget in Live Media Setup (i.e. in the panel)
The pastebin widget is a very nice tool to easily share pictures and text with others. See here: https://userbase.kde.org/Plasma/Plasmoids#Pastebin_Widget and here for a demonstration: https://www.youtube.com/watch?v=Rt4kpLlKzFk
Since one might encounter unexpected errors during install or even used the live session to troubleshoot some thing. The pastebin widget would then be very useful to share information via IRC, chat, etc.
Currently the pastebin-widget isn't even available in the ISO. Furthermore (after pacman foo) plasma crashed after trying to add the widget to the panel. The latter will hopefully change with Plasma 5. Still I think it is important to add it by DEFAULT to the panel, otherwise the chance of encountering it is very slim.
