Notes
floating window doesn't move when keyboard is open, keyboard covering the floating window display (better to use landscape mode for the floating window display to see what you're typing)
this app cannot open floating window more than one
you can hide the floating to the edge of the screen exactly like floating window on Flyme devices
you can't resize floating window, only change dpi of floating window available
enable sidebar function manually at the bottom of Mi-Freeform settings
