Please reinstate the Ctrl+Tab shortcut to activate the last accessed tab, or give a switch in “Options” to enable quick glyph comparison.
Right now it just activates the right-side tab, which is of little practical use.
What version do you use?
V 15.0.0.2980
Here it works as expected, so we don’t know what fails on your side.
Ctrl+Tab should move to the next Tab and Ctrl+Shift+Tab to the previous one.
The diagram on the first floor is how it works in V13.
In V13, you can quickly switch back and forth across multiple tabs in the middle by hover the mouse over a tab, left-hand clicking, and then alternating with your right-handed Ctrl+Tab.
In V15, Ctrl+Tab only supports activating the next tab, not the last accessed tab.
The following diagram shows how to achieve the equivalent effect of the diagram on the first floor in V15, where the mouse needs to move left and right several times across multiple tabs in the middle, which is inefficient;
I don’t think that will ever come back, but you can reorder the tabs by drag-and-drop.
