Control Bar is a control element on Gothru Overlay Editor that sets up on-screen buttons intended to aid visitors in accessing information and navigating the entire virtual tour. The control bar includes the next and previous buttons, share buttons, map, sound, rotate, Fullscreen, hotspots, photo, and VR link button.

Following are the steps to add a control bar on your overlay:

4. You can round the corners of the control bar outer border edge using Border radius. Increase the value in each field to make a rounded corner.  If you click on the up arrow in the border radius field, GoThru Overlay automatically adjusts all 4 corners at once. To adjust one specific corner, click on the respected field and enter the desired number. The following example shows you the amount of roundness at 15-pixel border radius.

5. Then set the position where the control bar is attached using Area. Defaults to 'bottom side'. You can also set it to a vertical position.

6. You can change the layout to wide and button separate by switching on the Wide and Button separate toggles to enable them.
