Just a quick update to inform you that today a user called clearmartin released a plasmoid called Redshift Control for Plasma 5.
In this new version of redshift plasmoid I’ve added a simple OSD that displays the current color temperature when in manual mode. The displayed information can be used to set a correct day and night color temperature in the settings page. Moreover, thanks to the contribution of some users, redshift plasmoid is being translated in different languages.
Finally I found some time to update redshift plasmoid.
The major change in the new version is the possibility to set the temperature color manually , a.k.a manual mode. To do so you just need to scroll the mouse wheel over the widget and immediately it switch to manual mode, starting to set the color temperature you desire.
