Using the old editor, I was able to quickly and efficiently add a new record by ticking the "Copy text selection automatically" box and then selecting the relevant terms in the editor behind the "Add record" pop-up. The new editor locks the UI so only the pop-up is accessible, meaning I need to go through a pretty significant manual process to add a new record by copying the source text and then manually entering the target term.
It would be super cool if the process worked more like it did in the old version.
Thank you!
