I noticed that in VS Code 1.85, tree views like the Explorer View now support sticky scrolling. How can I enable or disable this feature, and how else can it be configured?
It can be enabled or disabled using the workbench.tree.enableStickyScroll setting. The default value is true (enabled).
There's also the command View: Toggle Tree Sticky Scroll (which has command ID tree.toggleStickyScroll if you want to change the keybinding).
The other setting that currently exists for it is workbench.tree.stickyScrollMaxItemCount:
Controls the number of sticky elements displayed in the tree when #workbench.tree.enableStickyScroll# is enabled.
You can find the related issue ticket at Tree: Support sticky scroll #161207. Related release notes are here. You should later also be able to use the right click / context menu to toggle it (see issue #199381).
See also the Sticky Scroll documentation page.

The sticky scrolling can be enabled or disabled in the settings. Just go settings and type "sticky".
Enable / Disable like in the picture below.
