side-by-side-comparison Kate versus Visual Studio Code

On a eInk-display in text-mode, it is not so easy to catch the position of the cursor even if the cursor is blinking because on a eInk-display in text-mode there is just black and white, so a highlighted line in a smooth color (so between black and white) as visual orientation is not possible.
In the editor Visual Studio Code the width of the cursor can be customized.
The image kate_versus_vscode.jpg was made with a digital camera for a side-by-side-comparison. On the left side there is the editor Kate with a cursor, and on the right side there is the editor Visual Studio Code with a cursor with the value "editor.cursorWidth": 3. The image shows that in the editor Visual Studio Code it is easier to find the cursor position.

Possible solution for the settings
In the Settings, in Configure Kate..., in Appearance, in General, there could be a text like:
width of the cursor: ...

Remark
If this option will be realized one day, then one should have also a look at the https://bugs.kde.org/show_bug.cgi?id=468457, because if one decide to use a big cursor, then a big cursor will appear in all inactive views what can be disturbing.
