Composing an email that contains a link does not support link testing until the message is saved or sent to self. This limitation is noted to be intentional in the documentation. However, in good old Eudora, pressing a hot key while clicking a link in an email being composed activates the link for optional testing right then and there. Handy time saver. Filtering incoming emails via Tools/Message Filters works, but requires many needless steps to create a new filter. In good old Eudora, with an incoming email open or in the preview pane, the mouse option to "Make Filter" opens a filter creation window using the current email to suggest the filter options to use or replace, ending with a "Create Filter" button. So the first time you get an email from a buddy deserving a filter allows you to filter all future emails from the buddy as you wish - all while reading that first email from the buddy. Huge labor saver, and eliminates the need to remember the separate filter creation process required in T-Bird. I am a new user, so please let me know if I have missed useful options. Also let me know if this is a wish list that would be better directed elsewhere. Thanks!
