The web app's UI. I think the colors themselves would be OK with a regular font but the current one is so thin that it's barely visible. You should advertise your tool to other vim-leaning communities, like r/vim on reddit.
Although it might be less visible than having the description to the right of the heading, there is a description in the initial file that is shown. I want to keep the UI as uncluttered as possible, so I think I’ll keep it like this.
