You might have ever seen a menu panel that is open by sliding from the left side edge on many apps. You can make this kind of interface with Sliding drawers in Total launcher. There are totally 4 different sliding drawers for each side of the screen: left, right, top and bottom and you can enable each of them for your needs in Launcher options > UI & Animation.
When you enable the left sliding drawer like in the above picture, you can pull out the drawer from the narrow invisible trigger area on the left edge of the screen.
Long press on the empty area of the drawer or press the edit button on the top to resize the width of it. You can change only the width for the left or right sliding drawer while only the height for the top or bottom sliding drawer. If you want to expand the drawer to the underneath of the system UI (status bar and navigation bar), turn on "Overlapped system UI" in Launcher options > UI & Animation.
There are some options to change the background and to define the actions when it is open or closed. Press the options button on the bottom-left side of it while editing the size.
- Background : Background of the sliding drawer.
- Stretch background : Stretches the background image to fit the sliding drawer size ignoring the original aspect ratio of the image. When this option is off, the background image is crop to fit the window size keeping the aspect ratio of the image.
- Action on open : Set an action to invoke when the drawer is just open.
- Delay of action on open : Delay in milliseconds to invoke the action on open.
- Action on close : Set an action to invoke when the drawer gets closed.
- Delay of action on close : Delay in milliseconds to invoke the action on close.
