Thanks for taking the time to write this up — your request to let residents adjust animation priority in-world (so you’re not stuck with priorities chosen at upload) matches an existing Canny suggestion: “Animation Priority Change By User.” Since that one is already tracking the same idea, we’ll be merging your post into it so all feedback and use-cases stay in one place and are easier for the team to review together.

We don’t have an ETA to share, but adding your examples (e.g., cases where an animation overrides too much or gets overridden too easily) in the merged thread can help illustrate the impact and desired behavior.

I really wonder why we have gone for decades without this.. Priority is an additional datapoint that is added on upload anyway. so while for ease of compatibility it should still default to that why can't we dynamically change it? So much wasted space for multiple uploads of the same animation with the priority changed and so many animations that could be much more useable.

I wrote a more flexible proposal that includes this, as well as many other simple improvements: https://feedback.secondlife.com/scripting-features/p/llstartanimationwithparams-queuing-syncing-and-other-low-hanging-animation-enhan

EXACTLY!!!! Please make this happen SL!!!!

Additionally, there should be a way, by script, to disable all animations (such as when someone sits on an object or wears a scripted item) that have a priority of X (user-selectable number) or less, which will remain disabled until either the item is no longer attached/worn or the AV stands.

this would be great as many AO's have their priorities set way too high which causes some attachments to not animate properly,

For Example weapons like a gun's aim animations being overridden by the AO you're using.

Great idea, I think it would not only be beneficial to be editable on the animation itself, but also as an option in LSL animation triggers.

Yes, please!!
