May I (user) set the time defining how long the icons live?

Im a blakmagic player and the fire or ice state lasts 15s. I wanna display the skill icon in 15s. i found the code which defining "setTimeout" with 10000ms. May I have this fortune to use this addon with the time duration customizable?
I also found the animation-duration time which can only define how long the icon moves from one side to another side. But the icon always lives only 10 seconds. That is how it works now.

After downloading the html files into local, users can rewrite the "main.330c0e6c.css" file to set some parameters. Maybe the function which defining how long the icons live can be realized by add "opacity" in action-move function to combine icons life with the process of the action. Then when we get the html files into local, we can change when the icons fade away and further more how long the skills display. I have had this idea but I dont know how to realized it for my addon. Does anyone can help?
