Labels should toggle their button

[HeyMyian]

Issue title might be misnamed, sorry. I'm specifically talking about the "Comment" and "Synopsis" toggles in the Document Viewer:

They toggle only when clicked on the tiny icon. The label of the toggle could (should?) function as an extension of the icon. See HTML label tag, which this reminds me of: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/label

This is a button though, and not an icon. The alternative is to make the whole thing a button, or change it to a switch. HTML behaviour is not relevant. On the UI, clicking labels generally don't activate the function.

I believe this to be part of a larger UX issue.

I don't know if they scale with system settings, but buttons in novelWriter are small by default and therefore hard to click. The user wants the GUI to be as navigable as possible, else their creative focus gets interrupted. Clickable labels are one step towards that, even if the user has no accessibility requirements/configuration set.

Clickable labels are a feature of checkboxes and radio buttons, not tool buttons (checkable or not) in Qt. As I said, I can convert these to buttons with text.

Not sure what you mean by "larger UX issue" If you mean the project tree tool buttons and the new hideable toolbar in the editor, then yes, they are proportional to the text settings. You increase them automatically if you increase the GUI font size. A lot of the UI is modelled after VSCode UI.
