Disable collapsing/expanding tabs animation (via css?) while leaving animation enabled in settings?

[SXZ1]

Hello!
I am wondering if it's possible to disable collapsing/expanding tabs animation (preferably tab opening/closing animation as well) while leaving animation enabled in TST settings? I thought about using some css code but wiki only mentions other animations that can be disabled:

@Keyframes throbber {}
@Keyframes tab-burst-animation {}
@Keyframes tab-burst-animation-light {}
@Keyframes blink {}

Why would I need that? I believe that's gonna speed up collapsing/expanding tab stacks with big number of tabs as the code that slows down collapsing/expanding gets executed only when animation is disabled in TST settings.

Maybe try changing the values you want to disable:

treestyletab/webextensions/sidebar/styles/base.css

Lines 29 to 47 in b6fd8f4

	--color-animation: 0.25s ease-out;
	--indent-animation: var(--indent-duration) ease-out;
	--collapse-animation: var(--collapse-duration) ease-out;
	--tab-animation: background var(--color-animation),
	bottom var(--collapse-animation),
	color var(--color-animation),
	left var(--collapse-animation),
	margin-bottom var(--collapse-animation),
	margin-top var(--collapse-animation),
	max-height var(--collapse-animation),
	max-width var(--collapse-animation),
	min-height var(--collapse-animation),
	min-width var(--collapse-animation),
	opacity var(--collapse-animation),
	padding var(--collapse-animation), /* for extra margin on overlay-scrollbar mode */
	right var(--collapse-animation),
	top var(--collapse-animation);
	--tab-indent-animation: margin-left var(--indent-animation),
	margin-right var(--indent-animation);

I've just tried this code and it does indeed affect collapsing/expanding animation yet doesn't bring any performance improvements, unfortunately. Thank you very much!

TST's animations are disabled when you disable animation effects with the setting of the platform itself. It looks better choice if battery usage seriously need to be reduced.
