hi @AndersDeleuran sorry we missed this earlier.
What you show is the most unfortunate configuration, with horizontal tabs and text only. But I can see if you have it configured like that, the titles don’t make much sense.
Since in Rhino 8 these headers also function as the area to grab the container, I don’t think we can remove those. I think they could be hidden in locked mode though, is that your request?
I see what you mean, but that will only be possible when the tabs are horizontal. Floating containers always have tabs horizontal. Also they are more superfluous when tabs are text only or text + image, than with icons only.
