I would love it if there was a built-in wysyiwyg signature creator which formats signatures with what I assume is HTML code. That way you could upload content in columns - like with your logo left and your contact information right, as well as easily insert images for profile pictures and social media icons, etc. This should look polished and professional when done and it should be mobile-friendly / created with a fluid layout where necessary. I also want more font options from Google Fonts so people can match their signature to their brand - this should be easy to incorporate. Links should be able to be embedded and line spacing options must be incorporated. Some decorative items - at least things like solid colored vertical or horizontal lines, should be available for use. As well as basic 1 & 2 pt. stroke framing for the photos (square or round format) if desired. It is also important that the tool would allow for people to change the size of images and text within their signature to create appealing layouts. It is also worth noting that content should be able to go vertical - like listing out phone number and email, but also horizontal like creating a row of social media buttons.
