Don't show available dial slots when screen is full
As dials are added to a tab, the software ensures that there are always slots available to add new dials. This works great until the last dial on a fully maximized screen is shown, and then it adds a whole line of empty dials that are partially visible and a scroll bar. They way I work, I would rather user a tab until it is full and then switch to another tab for more dials rather than add dials to the same page with a scroll bar. The only way I can facilitate this currently is to leave the last dial always empty.

You can only turn off the option of adding dial slot in settings.
I didn't realize that. I had looked, but didn't see it. I looked again based on your reply and found "Show [+] speed dial button". Turning this off resolved my issue. Thanks.
