Is your feature request related to a problem? Please describe.
I use tellmewhen to create rotations for classes. I build a stack of icons that work as a priority list and use a meta icon to condense the "rotation" into 1 icon for display. The issue I'm having is that the spell cooldown icon itself only shows when a spell is off cooldown and ready to use. This creates a user experience where during the global cooldown, sometimes spells will popup over one another because they just came off cooldown. I have not found a way for tell me when to check if a spell is off cooldown in less than or equal to the remaining GCD.

Describe the solution you'd like
A solution I would like to this problem is for tellmewhen to be able to check if a spells remaining cooldown is <= the active GCD, otherwise the spell cooldown icon should work as normal. I cannot simply make a condition that says spell cooldown (spell) <=1 second because the global cooldown changes depending on haste.

For example: Say you have a global cooldown of 1 second. You are going through your rotation, avatar will be off cooldown in 0.7 seconds. Your global cooldown is active because you just pressed another ability. This makes avatar popup with 0.3 seconds left on the global cooldown. The goal would be that avatar appears even if it's not ready, because it WILL be ready by the time that global cooldown is finished.

I'm still searching for a solution. It's very possible I'm overlooking a simple solution or existing feature.
