I think it would be more user friendly to show the status of the plugins (not running/ bypassed) on the plugin block itself, instead of a corner at the bottom of the screen. Color luminance might be used for that purpose.
I second your suggestion. In the meantime, since this problem is present only in the Routing Diagram view, one can quickly toggle from Routing Diagram to Table View to check plugin status using ctrl+shift+x (or another shortcut, since you can configure it).
Need visual feedback at the plugin in Wiring View.
