Why does LastPass take up a full toolbar line in Internet Explorer?
This is one of the toolbar modes in Internet Explorer, but you can change it by going to your LastPass Icon > Preferences and selecting another mode. You can also view the LastPass icon in the Internet Explorer Command Bar by enabling the Command Bar in Internet Explorer. This can be done by going to Internet Explorer > View > Toolbars > Command Bar. Then, by going to the Command Bar > Tools > ToolBars > Customize..., you can customize where the LastPass icon sits within the Command Bar.
