Link behaviour in composer is a bit awkward. At the moment clicking on a link when composing an email by default opens it - but you're more likely to want to edit it. It would be great if 'open link' were kept to an option in a context menu and default is to edit, or do nothing with edit also in the context menu. This would also help with linked images - it's impossible to resize them with the resizer because clicking the slider takes you to the destination URL instead. Cmd+k is useful but doesn't work for the resizing scenario - also it's not easy to find out about!
