Hi Rey! Glad you find it useful!
I do understand your perspective and concern about the double click making us enter the “hidden” mode (Turbo). I guess that in a reverse clicky will always be hard to control the amount of pressure and the timing to make it act correctly.
Some time ago I made some demonstration videos with the guppy3drv firmware by doctor Jones. In this driver/UI you can choose some configurations where you can double click for turbo from any mode and a half press takes you back to the previous mode.
I tried to demonstrate that you can “manage the timing” of the double click, but it is true that it is not always possible to get it right.
However, take a look here.
Maybe there is another option instead of 2 fast clicks, but I really, REALLY, think that having the possibility to enable/disable a double or triple click to turbo would be awesome in a reverse clicky flashlight!
Hope this helps 
I also made another video showing it with forward switch but I guess it will not be useful in this project.
