often if not always do i see myself in situations where the gumball is needed but gets in the way right after some actions. toggling the gumball with a shortcut feels still a bit heavy in the workflow.
now if i could grab a few points or an object which i want to move/scale and have the gumball appear with an additional key like alt which i initiate before or during the action and can simply let go again to hide it would be less distractive.
yes it has a few, but hotkeys can also be situation dependent.
for example alt on its own does nothing, only during a command it toggles the snaps preliminarily. so if something is selected either entire objects or points and having alt pressed could trigger the gumball. that would not interfere with anything but would be a handy amendment.
alt is of course also used to duplicate objects, but here the object is selected and already in movement before i tap alt, so also not interfering.
