@Aquamaofian, thanks for resurrecting this thread! This is a great question.
In the time since this first post we made a lot of progress here. Instead of building this functionality natively into widgets, we built a custom widgets feature that allows you to build the exact widget you’re looking for from scratch. I’m not aware of folks manipulating widget size and font size, but I’ll check with the rest of the team and see if there are good examples out there in the community.
You can learn more here. You should also check out the custom widget category in the Community, and download a few custom widgets as examples from the Library.
There’s also an old school method for this that we called the “SVG Hack”, which was the option before custom widgets. Check out that video if you can get custom widgets to work.
