Hi Rene, that looks like a very useful Chrome extension. I hadn’t come across it before. I usually use the browser’s developer tools to look at the element structure: right click on an element and then choose ‘Inspect’ or ‘Inspect element’. But I like the simplicity of the Selector Gadget extension.
Note, however, that sometimes you will still need to examing the HTML structure. In the case of the page you posted, https://www.oval.nl/nieuws, the link element wraps a whole block of content:

Feed Creator will need the
<a href="[Item URL]"> element to either be selected by the item selector itself, or to be a child element of the selected item. You can select those
<a> elements with SelectorGadget but it’s a little fiddly (the
<div class="news-block"> element is the biggest target), and without examining the source HTML, it’s not immediately obvious why you would need to select the parent
<a> element for Feed Creator to work.
I think in the vast majority of cases, the extension will make it much easier to select elements for Feed Creator, but in some cases you might still need to examine the source HTML if things don’t work as expected.
