---A problem I encountered.
My screen resolution is 1920x1080 and that might explain the problem I have.
In the tab Charts, there are two drop-down menus that are nearly impossible to see on my screen and that I found by pure experimentation. The first one is with European scripts, etc. and the second one is with punctuation, etc. . It maybe due because the border at the left that contains them cannot be widen when I move the cursor around this border even though, in such a case, the cursor does change shape to but this new shape of the cursor does not work to widen the border at the left.
So, it is not possible in the tab Charts to widen the left part containing these two drop-down menus and whose border is the border for the table called "Unicode, hexadecimal and entities".
In the part "basic view and output" in the tab Charts, the part with Multiline, etc. appears only to the right after a long scroll horizontally.

This review is for a previous version of the add-on (2.6.7).
