Hi, my name is Sarah, I’m the Product Manager for Logo Maker. First of all thanks a lot for this important feedback.
Unfortunately we do not support the ability to upload fonts at the moment, but we do plan on supporting this in the future. However, the “Roboto” font is very close to “Arial” and may be a sufficient substitute in the meantime. Let me know what you think.
As to your second point - you can most definitely upload more than one icon to Logo Maker. You can add as many elements as you’d like, including multiple shapes and text elements. I’d love to hear what you think about it.
Thanks again for your feedback, have a great rest of your week!
