The template designer is clunky:

1. I can download MJML but I cannot upload it?
2. I can make themes by adjusting the font presets (Header, Paragraph) but how do I maintain themes across templates.
3. I can make the selected text bold, but when I change the style from paragraph to header or so the selection is ignored and the whole section is changed.
4. The color selection in text styles does not accept double click.
5. The font size selection in text styles is super weird, I am not even sure what it does.
6. Most text inputs apply the change immediately, which is supper annoying when you change the font size by entering a value.
7. The editor should maintain a list of recently used variables. 8 The list of used colors in the color selector is often missing colors.
8. The align button should show the current alignment.
9. I am not sure if "Discard Draft" really works. I wanted to revert all my changes but it was not working.
10. Line-height is weird. It should automatically adjust the line height to the font size, when you change the font size, because otherwise the text is cropped on some Mail clients.
11. When I download MJML all styles are inline, making it super hard to change the general theme because no CSS is used.
