Change icon of toggle property editor

[bjarnef]

The toggle property editor originally started as a checkbox and has used the square-check icon:

But since this is no longer reflected as checkbox, would it be better to use toggle-right icon instead?

Besides that I wonder if we should use container queries, so it adjust items per row in small overlay, as it doesn't align nicely with several lines of text.

3 or 4 per row looks nicer - personally I prefer 3 items per row in small overlay.
