FLOSS v1.3 contains bug fixes for the LOS behavior and a new icon. 

Change log:

Fixed: When target is prone and attacker is higher and line of sight passes through a target-adjacent woods one level lower than the target, that woods should count towards cover.

Fixed: When visualizing field of view (when touching the attacker/gold pin) and LOS runs down a spine to a hex, the hex should always be colored as if a hypothetical defender in that hex chose the side of the spine with more cover.

Fixed: LOS lines near hex vertexes should more consistently include or not include those hexes.
