I’ll be DMing some more 5e soon and I want to take the opportunity to try some different ways of playing (I’ll post my own suggestions as comments so they can start their own discussion threads). What alternate rules have you tried that you thought worked well? They can be larger changes to the game or little QoL tweaks (though if you can respond to the suggestion with “at this point just play [different game] instead” then that’s probably more than what I’m looking for!)
I track how long spells or conditions last by just scribbling down the condition and a duration on my initiative sheet.
For example if the Barbarian rages I’ll just write “Rage - 10” and each round I add a tally, when we hit 10 it’s over. So there’s no “extra” tracking, if someone delays their turn I just add a tally mark.
It might be a bit harder on digital tabletops if you have to go in and edit things.
