Simultaneous file saving output.
Usually I save one excel file into an htm and pdf format. and I have to repeat the process of saving. How about there could be an option where a user can save a file simultaneously to different outputs. In my case. If I could save my file as an html and pdf at the same time, that would be truly helpful in my work. Totally saves a lot of time.
A good way this is done is illustrated by Adobe Illustrator. You export each artboard to different image formats simultaneously, including SVG, with only a few keystrokes or clicks.
