Is there a way to go back to toggle the visibility of tray icons in Xubuntu just as it was prior to 14.04 since now Unity indicators replaced the classic tray which I very much dislike because now one cannot show/hide certain apps.
I did a search in Synaptic but couldn't find such a package.
You can selectively hide Unity indicators with the Indicator plugin. Right click on the indicator plugin and select Properties. You can toggle the Unity indicators independently, and completely disable application indicators in the same way.
Please let me know if this helps.
