I just noticed that if I highlight existing text, then go into Edit->Make Link, it puts that text into all three of the boxes - I expected it to go into the Link Text box. I presume this is intentional - if it is a URL and you decide to make it a link, you can just edit the Link Text box, or same for an LJ user. I just remembered it being differing before I did the upgrade to 4.1.2 (which was from a few revs back.) I grep'd the Change Log but didn't see this.
And a suggestion - place a box around the 'Using journal' UI - I went a little crazy trying to find how to change the journal in the menus, until I just clicked on the text on a lark. The box shows up when the mouse is over the text. This is on RedHat 8.0, if you want versions of anything just let me know.
