If you're finding you need to scroll the toolbox to get to the tools at the bottom (maybe you're running on a laptop with a smaller resolution?) then you might be tired of seemingly having to scroll the toolbox up and down, whether it's by using the cursor keys or the scroll wheel...

You can get around this easily enough by right-clicking anywhere on the toolbox to raise its context menu, which looks like this:

Depending on your screen resolution switching to "Small icons" might do the trick, keeping everything in a single column. However if not then you can choose "Two columns" which definitely will do the trick, making sure you can always see all the available tools:

Hopefully that'll help smooth your workflow if this has been affecting you!
