Focus mode: add the ability to higlight current line where cursor is

[marek-lach]

Should be optional in Settings, under Highlighting, but a subtle highlight of the active line where the cursor is may help some, to focus better.

For illustrative purposes:

I can certainly look into it. There is a code example here: https://doc.qt.io/qt-6/qtwidgets-widgets-codeeditor-example.html

In general, manipulating the formatting of individual lines in the editor tends to be computationally costly from the Python side of things, so it may not be doable. I can give it a try though.

Do you mean only for focus mode, or as a general highlighting feature?

More as a general feature, not just for the full screen mode. However, if it’d prove too costly, or complicated, then it may not be all that necessary...
