suggestion to add some syntactic sugar to /timer

Currently /timer is useful to me but it takes a macro slot and is sorta janky. I would like to see /timer replicate the actual time of a disc/aa and give it a more consistent feel.

Like this:
/timer /disc Cool Guy Disc rk. CDXX
Or
/timer id:7
Etc

Ideally it would fully replicate the timer, especially in the case of AA that can proc a refresh; or red itself out if the same time id is used on another ability

and persist through zoning.

You can use GINA for this instead. The in game timer is too rudimentary for anything significant.

I would love to use Gina, if only it didn't require windowed mode

It's worth it & you can emulate full screen mode. Can also use WinEQ 2 lite to help with that if you like & it's free as well.
