You can kinda make alerts in ACT and I think there's a mod to do it more efficiently(spelltimers? try googling that iirc that's what it was).
That's why I hate Bard though and never play it more than just get it to cap, I fucking hate all the maintenance on top of the procs to watch for, can't relax at all playing it. Meanwhile you can play MCH and you never really "miss" anything, worst case you forget to press a cooldown right away and you'll drift a bit compared to raid cooldowns but for casual content it doesn't matter/people are terrible at lining up cooldowns anyway, and rest of the time you just press the buttons as they come instead of having to keep track of several different timers.
And the song stuff doesn't work I believe, haven't checked the balance for bard in forever though but last time I did you had to cut the 3rd song at 20secs cause songs were 80s cd, so it doesn't line up after one rotation. Might have changed though they buffed paeon or whatever the skillspeed song is to do stuff once it wears off.
