Well I have modded mine to have a camera so I can monitor the print remotely (Cant attach photos if anyone is interested, running off of an OrangePi), so I have would like to have a tab setup to show the camera, status of the print, etc... Also would like to set it up so when its done printing it can send me a notification via HA and flash the lights in my office to let me know its done.
Once I have done that much done, I will probably have more ideas flowing on things I can do
