   * Monitor-UI or panel should generate periodic (configurable?​) events for polling external events that are then propagated to Monito-logic objects. Doing this centrally in one place, reduces the number of CPU wake-ups.   * Monitor-UI or panel should generate periodic (configurable?​) events for polling external events that are then propagated to Monito-logic objects.

 +    * The idea is nice and I thought about that too some time ago, but then there are plugins that update their widgets quite frequently and more frequently than others, so the questions here are more like: "Is it worth all the engineering?​ Does it really make a noticeable difference?"​ Maybe it makes a difference in powersave mode, if such a mode is planned. But how big are the gains in reality? One positive side-effect would be that all plugins update at once, which might perhaps look better and less chaotic, I'm not sure. On the other hand, could it lead to bad effects when all plugins update at the same time (jerkiness,​...)?​ I'm all in for a central place to configure or enable general powersave mode, however. But then the plugins themselves might need to decide how to implement powersaving. ​ --- //​[[h.judt@gmx.at|Harald Judt]] 2013/03/19 21:25//

 +  * Idea is the plugin shows preferences for the widgets:
 +    * set their position, therefore the static names for both multiple items (in case of example the sysload plugin), but also the position of the indicator items (by default icon/​progressbar,​ label).
 +    * Plugins can pack a widget (vbox or a single frame) for the plugin specific settings.
 +    * Color settings for progressbar and label.
 +    * Graph appearance.
 +  * An option would be a xfce_panel_indicator_item_add_width (XfcePanelIndicatorItem *item, const gchar *name, const gchar *display_name,​ GtkWidget *widget); to pack custom widgets. No idea if that is really useful and would affect the '​standardization'​ we try to accomplish here.
 +  * Plugin is responsible for the updates (so its own gdk timeout).
 +  * A graph widget could be a nice addition. It would at least merge the cpugraph and sysload plugins, making them both more functional (also graph of memory/swap usage), but also the netload and diskperf plugin would benefit. Bit of fancy cairo and transparency wouldn'​t hurt here :-).
 +    * Xfce4-taskmanager has a nice widget already.
