Links to external pages should open in a separate tab, so users aren't forced to leave your site on click.

Some elements in the theme could be better rendered at smaller device sizes.

Suggest:

• increasing padding from viewport edges to 20px
• reformat 'changelog' items so that date sits above content, not alongside
• adjust changelog item width when list is expanded (when viewed in iOS Chrome, items fall off screen, forcing elements wider than viewport width)

On iOS firefox/chrome, touch events are either firing every now and then, or not doing anything at all. Touch reveals aren't working as intended most of the time.

It might be worth reviewing the touch event handler in your js, or looking for a CSS-only solution. Perhaps better, don't hide content from the outset and style all elements as open from the get-go!

Run theme files through https://validator.w3.org, some errors/warnings exist.
