If you want to try before you buy this tweak you can install the tweak “Assistive” instead which is a light version of this tweak.
Assistive is a customisable always-on virtual home button just like "assistive touch". Except way better!
Features - Tap the button simulates home button - Double tap the button simulates .. double tap the home button - Triple tap locks the device - Hold opens up a four way panel, release on any button to execute that command. - Reassign what command goes where in each panel (see above) - The above thing integrates with any FlipSwitch toggles you may have installed. - Automatically fades out to not disturb you. - Adjust the size and colour of the button - Snap to edges, or don’t.
