Shorter/slower tab scrolling distance.
The scrolling of tabs from left to right using the mouse wheel is way faster than I want. One scroll of the mouse wheel moves the tabs like 80% of the way across the tab-bar. This is problematic when the browser window is sharing half the screen and a scroll moves all visible tabs away. This means I have to then click the buttons to move the tabs one-at-a-time and if I click too fast it scrolls an entire pages worth which is also unwanted.
TLDR: I want a setting like `mousewheel.default.delta_multiplier_y` that only works in the tab-bar.
