Space is at a premium, for many of my Layouts ... the panels are fairly thin. The new dynamic tabs are so wide due to their labels that they disappear (into More) when the panel is not wide enough.
Please provide a USER-option to toggle the use of Icons which are more compact, that represent each of the dynamic tab names (with hover to show the names ;~).
Also, please do the SAME thing, where possible, for the Sub-Toolbar that a given dynamic tab opens ... for the same reason ... making best use of space for thinner panels.
