Toolbar Scrolling Without A Mouse

Hello! I would like to suggest a small improvement.

Currently, some toolbar options can only be accessed by scrolling with the mouse wheel. This works well for users with a mouse, but it makes those options inaccessible for users who only have a touchpad or keyboard.

It would be very helpful to add an alternative way to scroll the toolbar, such as a visible scrollbar.

This would improve accessibility and make the app easier to use for people who do not have a mouse.

Thank you for your great work and for considering this suggestion.
