I like to have visible separators between what I consider different sections of my panel. currently I use a different widget but that adds extra spacing between sections and I'd rather have only the spacing from the margin separator (which i have to use because it makes the sizing of different sections better). the margin separator is shown in the configuration menu as being visible, but it isn't. the look of the panel with it invisible is fine too and obviously that should stay an option, but it'd be nice to have the option to make it visible or maybe a different widget (pre-installed) that works the same except for being visible.
Hi! This goes beyond the scope of the margin separator, which is exclusively meant for, well, managing margin areas. The margin separator, when not in edit mode, does not take any space; you should instead use a third party (visible) separator widget for this, as it should be able to make them arbitrarily small so that they don't take extra spacing.
