Ages ago I changed shownick in KTX and ezquake so output looks like teamoverlay, one may found it useful.
By default KTX use old shownick, to use new version you should call it like "shownick 1", you may test it in prewar. ezquake have scr_shownick<press tab here> variables, similar to teamoverlay so you can tune it out.


It looks like this

teamoverlay has to be on for this to work? and it'll be automatic on hover or?

Nice.

But looks like it doesn't allow showing the ammo count, which makes the old shownick better in practice.

1) Independant of teamoverlay.
2) Its not automatic, you have to issue same shownick command as usual, but with some parameter, like "shownick 1", its not variable but command.

well, yes, for some reason there no ammo info, probably because teamoverlay does not use it too, not like its impossible to fix.
