When I try to insert a link, I have a tab open with the page I want to link to, to avoid errors.
If I click the link-link, I get a dialog, where "http://" is already filled in. But to cut and paste my link, it would be more easy to mark the whole link, and paste that, instead of twiddling around with the mouse.
Note that there are two standard ways to copy/paste in Linux, one is more comfortable: You mark a text - in this case the url in the browser. You just mark it - no Ctrl-C or something requiered. Then you place the cursor at the target place, and just hit the middle mouse button. Whatever is marked is now pasted to the place where the cursor is. But the pre-marked field "http://" foils that attempt, because now, the last marked text isn't the url in another tab, but the useless text "http://".
- let the field empty. (my preferred idea, should simply work)
- give two alternative link fields, one with http:// but not marked, one without. I guess the "http://" has two purposes: make clear what is requiered, and help those, who like to type. Well, of corse, sometimes it is https. :)
The first idea is always the best one. :)
