We are actually beta testing this right now, and will release an update within a week or so. It has actually been very difficult due to having very complex list virtualization (so that thousands of items can render without slowdown). But we have a new list virtualization system which enables this (and makes a ton of other things easier).

Font-choice is obvious and relatively easy I would have thought. It can change the entire feel of a product, and is probably not just value-additive but value-multiplicative.

The currently used Font makes it harder to read texts. The characters are very close to each other. When you look at the Font "Whitney" for example (Dynalist is using this Font), the text is MUCH more pleasant to read.

Google Font choosing is must. You could give different feel of your Moo.do workspace.

I need fixed width font type, or even better if can choose different font, in business, we prefer to fixed width font, or 'courier new' , etc.

I would also appreciate the ability to change styles.

At the same time, the size is the most critical thing for me personally. I use a high resolution display and the font is super tiny and unreadable.

This would be much appreciated - I'd personally like it in fixed-width, but each to their own.
