Little bar at the bottom of your screen that shows when your double-jump is ready. Disappears when you use it, flashes yellow when it recharges.

I made this because I kept burning my double-jump and then trying to use it again like an idiot. Now I just glance down.
The bar sits centered near the bottom. Cyan when ready, gone when used, yellow flash + height-stretch when it recharges. Ground jumps don't count, only the actual mid-air boost.
It also hides itself when it'd be useless or annoying: in a titan, mid-embark, on the dropship, on the spawn screen.
Manual install: drop the folder inside mods into R2Northstar/mods/.
Open ModSettings ingame to move it around or resize it.
There's no built-in "remaining jumps" thing exposed to scripts, so I had to fake it by watching your vertical velocity. Touching ground or a wall = jumps refill. Big upward velocity spike in mid-air = that was a double-jump, mark it used. Walking off a ledge keeps both jumps, same as the game does.
It's purely a HUD thing - doesn't change your actual jump count or affect anything else.
