Following on from AppIndicator Applet won't scale icons on top panel our appindicator applet now supports reducing its icon size when the panel size is reduced. This allows panel sizing down from around 40px to 30px.
In addition - this bad bad bad appindicators that show huge icons should now be displayed with normal sized icons.
Right click actions have been disabled to be consistent with normal budgie applets.
Just update on eoan to get v0.6.1 of budgie-indicator-applet
