URLs in editeng are fields (while in Writer they are just character attributes). That means, the cursor can't travel through them as they are represented by a single character internally. This makes URL editing hard compared to Writer. One has to right click on a link, select "Edit Link" and then update the link text. Instead it should be possible to directly edit the URL text as any other text (and as it is possible in Writer). Probably we can't get rid of the field nature the URL currently has (to not break API) but we can surely add inline field editing as we have in Writer for certain fields.
it seems like a good enhancement
