### 5/5 — Potentially Note App of Choice

*2022-11-05*

This app has done so many things right so far. It is impressive. It’s like Zim desktop wiki. When CSS is added, Ill be able to fix the skin. It’s got a jet black background and the text seems to be stuck on a hard to read serif font. Please add a sans serif font. The code blocks, tables, text editing are all great. I would suggest copying a pre made dark UI palette so it has less contrast. Google uses #121212, for example, instead of black. 
A desktop version that syncs for a subscription fee would be cool.

### 3/5 — Very Promising

*2021-04-16*

What do you want

- note links
- bi directional links
- images

We have it here :). 

I would give 4 - however documentation on how to do some operations like adding images not clear. I will keep this on my homepage
