I'd really love to see a 'time remaining' indicator, even if it's just a small visual or audio cue at the end not a whole new graphic, for channeled abilties to help know when they're about to run out. I haven't tried all the pacts yet but I've leveled Sirin and Orengall to 30.
Sirin's butterflies/invisibility it would be great to have a way to know when I'm about to run out of that for if I'm using it for pickpocket and not trying to get stealth kills. Similar story for the big head illusion, to know roughly when it's going to explode to be able to help me plan around using it better.
For Orengal in particular, knowing how long I have left on the wolf form so I know if I need to commit to an execute instead of spending more time stalking trying to find the ideal target and even more so if I'm using it for overland travel. Would also be great to have some kind of indicator how much longer my spirit wolves are going to stay with me (if I have one with me, are they good or shoudl I pop another summon before I go into a fight, don't wanna have him dissapear mid battle and then I lose my passives if there's a way I could be aware of that being a risk I choose to take or not).
Very minor little thing, but it's been a point that's come up while was playing as something I'd like to see. Made me think I should say something when I saw a youtube video of someone talking about Orengal and how they were also annoyed there was no cue for when you're about to be popped back to your Envoy's original position while in the wolfwalker form thing
