      This is a common UI flaw. Twitter search does it too. Human reaction time is about 50ms. UIs could quite reasonably detect if the button that gets the click/submit event has been there for under 50ms, and just not action it, with some nuanced indication that that's what happened.https://twitter.com/li_haoyi/status/1236896391995084800 …

      The feeling when you type “intellij” into Spotlight Search, and it shows you Intellij IDEA, but just before you can hit Enter it decides that what you really wanted all along was to open up intellij-platform-support.xml using Sublime Text

      It’s around 200 ms rather than 50 ms

      Yes, someone else pointed that out to me! I was confusing it with the time lag starts to get annoying...

          50ms is roughly the delay between pressing a key and the bits finishing to cross the wire – add another 100ms until they show up on the screen. Depending on the task, humans can make out delay in the single-digit ms range:https://www.youtube.com/watch?v=vOvQCPLkPt4 …
