I found a little UI bug/glitch about tabs. It happens when the option "Folder Tabs" -> "Tabs on multiple lines" is unchecked.
- Open new tabs (on directory) until the tab header is almost filled, just before the buttons "<" and ">" appear automatically
- Activate the last tab
- Navigate to another directory, which its name is really longer than the current one (e.g. from c: root, navigate to "C:\Windows\Downloaded Program Files" using CD on command line)
To see the whole tab name, by example, hit CTRL+SHIFT+TAB and then CTRL+TAB.
