Widgets

For widgets, in unlocked/edit mode, you need to delete the widget (if already there and wanting to replace), then add a new widget in its place.

First go into Total Launcher's Options ->UI & Animation -> and un-check 'Keep window order'.

Go back to your page where you want the widget, then tap the empty area you want to put the widget several times quickly to make sure that window is selected while background windows are unselected (there won't really be any indication it's selected, but it is. *Don't long press to highlight the window.)/(Alternatively, long press the empty area you want to put the widget, click the settings button on the window, then back a couple times until the window is no longer highlighted), then add the widget by clicking the '+' button in the upper right and selecting the widget you want and resize it into place (if the widget is not resized to fit within the window, it won't stick). When done, re-check to 'Keep window order' and turn the edit mode off. Here is a video to follow along: https://youtu.be/NM7Z55IY0NI

Don't forget to continually make backups of all of the changes you want to keep so you have a restore point in case you make a mistake editing.
