Seems that every time I cancel the movement with the Gizmo-less shortcut by pressing ESC, everything disappears. When I press the shortcut to Transform, everything reappears again.
Also, it would be nice to have the Gizmo-less transform behave a bit more robustly. Currently when you start moving something with a hotkey, and then turn on an axis lock X, Y or Z, it keeps the transform that you did in screen space, whereas the transformation should be reset and start from the initial point when pressing X, Y or Z... I guess maybe looking more closely at how blender does it would be helpful.
