Now that the customizable taskbar update has been released, it would be useful to have the ability to resize/adjust the length of the taskbar sections left and right in order to make room for more or less tools and colors. That way instead of having a user scroll through a bunch of colors, they can just adjust the section bar to the left to reveal more of their color palette.
[Similarly to how Window PC taskbars have the “bars” that adjust icons left and right.]

It would also be great to have an option to lock the adjustments as well.
