Glad you like it, thanks for the input. I retired my addons last weekend, they'll stay online as long as possible, but you may be interested in the just-released userscript version of Copy Selected Links: https://greasyfork.org/en/scripts/469506-copy-selected-links
Its UX is a little different but I found it quite interesting to develop and start using, and it seems to work more reliably for me. If userscripts are within your abilities to install and use, I'd actually appreciate a first user and initial feedback. I use CSL, DID, and IBCP myself so I'm actually interested in keeping those maintained as userscripts without all the hassle of publishing whole addons on the big addon stores.
