A few things I noticed when trialing.
1. Left sidebar, second icon. What's it supposed to do? I'm assuming maybe export but the button doesn't do anything. I couldn't find export at all either, so I'm not sure if it's broken on my machine or if it's a limitation of the trial.
2. The block type options (paragraph, title etc.), I'd like if the options looked more like buttons rather than just plaintext fit in a box. Just a border around the options (or optionally a background color for them) would already be very helpful.
3. Contrast. The left sidebar icons have very low contrast. The border around the blocks also could use a stronger contrast. I wouldn't actually mind seeing each block's borders at all times just to have a visual outline where one ends and the next starts.
4. I haven't tested this, but does the app support different types of citation standards? Both for the source list at the end as well as the inline references inside a text?
5. do we have any type of control of the final exported product? Can we make our own template with fonts and everything set in place or will I have to export it to LaTeX first?
