The title combines two discussion threads on this board.
I have adapted the first solution in post 29 of (1) to a report template (with some alterations: constant box placement and altered text). This works as shown in (1) but to me rounded corners on the inner side of the margin boxes would look much better.
No (2) has some solutions to specify corners separately.
I tried a lot to bring (1) and (2) together but as a tikz beginner I failed. I could either control the colors or have rounded corners on the inner side, but not both.
Is there any solution to the following? In a twoside report: Display the chapter title (or some other text)
- in a rotated box at the margin
- with constant placement and size (or moving as in (1) )
- with rounded corners on the inner side of the box
- with predefined box fill colors changing in every chapter.
Best wishes
