HUD activation not completely consistent with Launcher/Toolbar/App lens activation

To activate the HUD from an app, you have to swipe up from the bottom of the screen until the HUD button appears, and then continue your swipe until the finger is on top of the button to activate it, and then release.

For a toolbar, or for hiding the hud, the behavior is slightly different and those are shown/hidden depending on the position where you release your finger or the speed and direction of the swipe when releasing. Something similar happens for the Launcher, if you swipe further to the right when the launcher is fully visibile, you go to the apps lens.

Can this behavior be tuned so that you don't have to exactly position your finger on the HUD button when releasing? Now you have to "hover" over the button to make it "active". For example, the HUD button can be active if you hover over it, or if your finger is in the part of the screen above the HUD button. Like that you can quickly open the hud by doing a fast long swipe upwards without paying attention to where the button appears.

Summary: I want to do a fast long swipe up from the bottom-edge to activate the HUD. If I want to activate the HUD really fast like that now, it is very likely that I 'miss' the HUD button and don't activate the HUD

This is being addressed through a new persistent behaviour of the HUD icon
