Toolbox: no way to know when tools are not displayed because window is not high enough

Summary:

I just got an email by a user who was desperately looking for the new Page tool, and could not find it.

This is because there is no indication on the toolbox that there is more content farther down / or how to get to it.

Steps to reproduce:

• open Inkscape 1.2
• adjust the window height so that some of the tool icons become invisible

What happened?

• user does not know how to find missing tools

What should have happened?

Some options:

• show a small arrow like before at the bottom
• show an info text on hover that explains that one can scroll, make icons smaller, make window higher, make toolbox wider to fix this
• show a scrollbar...
• move automatically when user cursor goes below the last tool
• display some other kind of 'scrolling goes on here' indicator at the bottom / top

Version info

Inkscape 1.2 (release, any platform)
