Small updates for Boundary++ — Stop Sign VR Tools Steam update #222226

StopSignVR / Boundary++ has been updated with: Boundary++: The amount of 'view blocking' is now configurable using the Settings Editor (the 'max opaqueness' settings). This is useful if you want to be able to see through the grid when a controller or headset is really close to the boundary. Boundary++: An Activation Distance Multiplier has been implemented. This allows for the default chaperone grid to come up earlier or later than Boundary++. Note that Boundary++ uses the activation distance configured for the SteamVR chaperone, multiplied by this new setting. (You can still turn off the default chaperone completely). Space Drag and similar features of other apps will not put the boxes in Edit Mode anymore. Some Pimax and Linux (work in progress) fixes. Currently, there's a 20% Winter Sale discount!
