I am a new Fedora 20 64-bit user and I used Gnome Tweak Tool to customize the appearance of the UI. However, I was not able to get the active application from the top bar. I am providing a screenshot to visualize the situation, Google Chrome is the active application and it is shown in the upper bar, I want that entry to disappear if possible since I already have a bottom bar populated with open applications. How can I do that?
The shell extension
TaskBar proved useful in my case, it can be accessed via this link. In order to disable the active application icon I went into the preferences of this shell extension then under the Misc tab I switched the slider to on next to the
Hide Default App Menu. I do not know if this is the expected effect of this setting but I achieved the desired effect. You may wish to look at the screenshot below:
