I do NOT like not seeing the slug that is used when I make an XREF. The new advanced editor Link editor only shows the article title when you select the article to be linked. I want to see the SLUG as well as the title. I also want to be able to manually enter or edit the slug. Sometimes I create a link to an article that has not yet been created, or I know the slug will change soon. The old editor let you do that because it let you edit the slug in the link. The new link editor doesn't allow that.
Another problem: this has always been a problem but now it's worse: When linking to a HEADING on the same page, the link editor has always added the slug and then the anchor ID. This is very annoying because it means when the user clicks on the link on the published page, THE WHOLE PAGE REFRESHES instead of just jumping to the heading.
I have always worked around this by NOT USING the "link to a heading" feature. I simply manually add the anchor ID in the link box. BUT NOW I CAN'T DO THAT because I don't have access to the slug when making a link.
I know of a workaround: I click the tab to add an EXTERNAL link and then add the anchor ID in the URL field. This works for now, but is it just a matter of time before you take that away too?
At a higher level I find it annoying that so many features keep changing in ways that are supposed to make tasks "easier" but in reality they only make it easier for people who don't know what they're doing. For people with experience working on web-based documents, we find this "dumbing down" of the features to be very annoying. This removal of the slug field in the link editor is a perfect example of this.
