Multi-line text, more abilities to write and format text.
We definitely see a lot of opportunities in this area. It remains however, very tricky to implement this in a easy and intuitive way. We experimented with multi-line code, with different font sizes within one text block and so on and we found that for example, scaling the text gives all kinds of unwelcome side effects (like the need to break text automatically, uneven scaling of font sizes etc).
We keep keen on improving in this area, but we would love to hear your input!
