I see… Thank you for the input and clarification for its intent. However, from a usability standpoint, having an instantaneous flip to a different tab from just a hover action seems like it would be confusing no matter the target purpose. Let me also add to what I meant by “fade-in animation”. So when I say to fade-in, I don’t mean something that takes 0.5-1.0 seconds to animate. I’m talking about approximately 0.10-0.25 seconds for the complete animation to start and finish. (final timing adjustments should be made by whoever is governing UI/UX for the team)
I understand that the purpose is to “preview,” which is why a fade-in animation is necessary to convey that concept. The best existing example that you may be familiar with is on Windows Vista/7 OS, when you have multiple windows open and layered on top of each other: When you hover your cursor over an icon on the Start bar that is not the current top-window, a preview thumbnail comes up. And then when you proceed to move your cursor over that preview thumbnail above the start bar, all top-layer windows fade out to reveal the one the cursor is pointing to in the thumbnail. You can see that the feature also acts as a “preview” option, and they successfully implement an animated fade-out to convey the sense that the window being shown is merely a preview, and that there are still windows stacked on top. (I am not sure if this feature is still existent on Windows 10)
Maybe whatever “bug” is in the current version will fix it, so I don’t mind waiting to see what the engineers come up with. But having been working with UI design for a bit (in apps mostly), my professional opinion is that some kind of quick fade animation would best convey a “preview” concept, especially for the tabs in this case.
Let me know your thoughts!
Edit: @Numpty So if I were designing this feature, I would say:
- Mouse hovering over non-current tab triggers fade-to-tab animation
- Animation lasts 0.10-0.25 seconds (requires testing for best “preview feeling” for timing)
- The end preview state of the tab is slightly dimmer, possibly RBGA value of (0.9, 0.9, 0.9, 1.0) but also requires UX testing with various kinds of webpages to fade into to find best values for “preview feeling”
