So it is easy and works like a puzzle Steps to Reproduce: 1.. 2. 3. Actual Results: . Expected Results: . Reproducible: Always User Profile Reset: No Additional Info: .
Here is an alternative idea, but I like this one better https://bugs.documentfoundation.org/show_bug.cgi?id=169640
And maybe you could even customise each border this way like change its colour, thickness, style and so on. I would absolutely use it if it existed as I imagine, nothing could be cooler than that
