It would be incredibly helpful if we could use Markdown in description fields.
e.g. instead of having to use the mouse to choose the header level, simply type ## at the beginning of the line for a level 2 header etc.
Dropbox Paper is a good example of this working well. Markdown is enough of a standard for this to be worthwhile.
I really like using Wrike as a note taking tool (for meetings etc) but the mouse-based formatting makes it rather slow.
