Small bug with the file browser. You can open and then immediately close it by double-clicking on the button. It looks like input isn't properly being masked when it's open.
What's being opened and closed? If you're opening a first child directory (in the middle section), you might be hitting the
.. that shows up right after.
I'd be interested to compare power consumption of those demos implemented in JavaScript.
Someone else also suggested doing that. It'd definitely be interesting to see but I'm lazy
I'd bet it's a lot lighter than an equivalent React app.
Did you write them directly in CSS or are you using something like SASS?
