Add option to hide tab bar
Whenever I use the terminal I rarely work with multiple tabs, so having the tab bar permanently visible is just wasted screen space (especially on mobile).
An option to hide the tab bar would be sufficient for me, but I can also think of other approaches to this issue. For example, you could only show the bar when more than one tab is active, or move the entire bar functionality to the side menu (adding new entries per tab, considering its currently not really used for anything else).
