I think this would be helpful for people making their own lineups especially when you're alone (aren't we all), if you're bothered by the traceline turn it off, like every other option. The viper smoke indicator in the map is really nice but, it only helps with abilities that have the same program. I play Yoru, the flash is kinda tricky, you can make one-way flashes, mostly you need a friend to confirm if the flashes even work on the angles you want to flash (me=dude who play customs alone), heck if you can bind a key to tp on the angle you want why not, or summon dummies (to summon, example you go to the oper spot, hold the angle and press a keybind, voila you have a dummy) that indicates the duration of flash or damage it received on top of its head (can be seen through walls ofcourse).

I think agents with grenades and flashes would really benefit from this, team flashes suck and I'm the one flashing them kek. Sure the creativity of making lineups would decline but hey it works easier, if you want to do the old school way turn them off.

Note. If these already exist please tell me how.

Edit. The dummy thing.
