Apparently, the hover tooltip style that was already present for the follow button, has now been added to other places as well.
One thing that really bothers me about these tooltips, is that they pop up immediately, distracting me when for example I just want to press the upvote button and have 0 interest in reading that tooltip. It also covers up the top of the question body.
Usually, UX designers have added a delay on hover tooltips, so users that know what they are doing aren't confronted by tooltips all the time. This has been present on the first computer I bought, and is implemented in nearly every program or website I use that has hover tooltips.
However, for some reason, on SE, hover tooltips are immediate and thus always pop up when you're taking a specific action, no matter if you're familiar with that action.
Could SE add a delay to the tooltip appearing, ideally one that's similar to what everyone else is using?
