First of all I'd like to tell you that I'm not a scripter so I can't help the development team with the technical part.
So our time spent on the server ( aka played time ) is already calculated. I was thinking about if we could have an icon where our played hours would be divided into the spawns we used. After some time, I realised that the time divided into "ALL" spawns you ever used can't be done because then we would get a badass long list. For this case I'd recommend to do the same idea but instead we could have a place where the TOP 8 most used spawns and the playtime could be seen.
I was thinking about adding another icon to the "M" panel.
After clicking on the icon, it would open a page like at the other ones. ( F.e.x : Music, Message, Clock )
The difference would be only the content of the page. We could have something like this:
This idea's function is only an extra thing to have, and I can't see if it has got benefits or not.
If it's possible, we could add already deleted spawns such as deleted squads, gangs, groups.
