The tabs easily take up all the space, especially in vertical mode. Then, any text on the tabs is not visible, and it’s very hard to understand what to click.
Possible ideas:
Maybe set some minimum size for a tab (e.g. 3 characters wide) and don’t make them smaller than that
Move tabs to hamburger menu when they don’t fit? (Maybe show a few first tabs and hide the remaining behind a menu button?)
Make tab bar draggable, so that you have to drag it to reveal the hidden part
Maybe hide the ‘Detach’ button behind a context menu (shown by right-click on Windows, long-press on Android?) — it’s not like it’s used often
