Thanks

I couldn't find these answers on DingooWiki

Should I also update everytime mine zImage and rootfs when there is a new version available?
I heard that there was a version which enables the power off switch within dingux.
You can...or you don't have to.
But, if you do...you also should update your dmenu.cfg file, using Notepad++ to give yourself the menu options to "Reboot" and to "Power Off" from Dingux.
There's other topics that discuss this, so I won't go into detail here. If you can't find them, PM me and I will try to help you, but, remember, I'm not too experienced at this stuff...I only know how to do stuff that I have already done myself, and can only solve problems I, myself, have run up against.
I'm no programmer, not by any stretch of the imagination.
