I totally love Gmail, but after migrating to Gmail from Outlook use a few years ago, I had a painful realization that I would have to do without my handy Outlook signature feature. I had used it extensively for years, customizing signatures for personal and business uses.
Gmail’s own signature feature is either on or off, and only one signature can be saved. Argh.
Firefox add ons to the rescue! Clippings by Alex Eng solved the problem. With this add on, I can save multiple signatures and choose from them on the fly by simply right-clicking in the Gmail message. Sweet! Although there is less formatting flexibility than Outlook, I’m mostly over it. Phew.
