alt Hacker NewsHere's a tip: any time you've got before/after screen grabs, don't do this thing where you've got to drag a line to switch between the two, don't have a fade, don't have a sliding transition, or anything like that. Just have it display one, then have a single button that you click to have it immediately display the other. Then when you click the button again, it goes back to displaying the first one again. Click, click, click - and your eyes do all the work for you.

Also: I can't work out which image is which. Taking the first image as an example: we've got MATERIAL-STYLE on the left, and LIFTKIT on the right. But what's the left? Does this mean that when you drag the line to the right, revealing the left image, you're looking at MATERIAL-STYLE? Or does this mean you see MATERIAL-STYLE when you drag the line to the left?

I always found this UI pattern a bit odd, because there just aren't that many situations where you want to compare the left side of image A and the right side of image B.
I see it a lot in photography, to show before/after processing - but what you want to be able to quickly compare are the same part of an image with and without the processing applied.
One of the photography tools I make is a LUT viewer/converter - and while I didn't have the slider at first, I guess it's standard enough at this point that people asked for it and I added it.
But I made two additions to it that make it more useful IMO:
- have labels on the left/right top corners, so it's immediately clear which version of the image you're looking at
- click and hold on the image to preview the full unprocessed version; release to revert to the view. That makes it easy to quickly compare the two versions of the same spot of a photo. (similar to what you suggest, but non-latching)
I have a video of it in action here:
I've been wondering that myself. The descriptions seem to indicate that fully dragged to the left is liftkit, but my first assumption was that would be fully dragged to the right.
I turned this into a game. Which image do I think looks better? Now I try to figure out which image is supposedly supposed to look better.
I agree, the x-axis labels are not helpful! Thankfully, the first example is “buttons with corrected icon spacing”, and the image on the right looks much better than the one on the left (a bigger difference in quality than in the other two examples), which is visible when the slider is on the left.
Suggestion to devs: put the label “material-style” in the lower left of its image and “liftkit” in the lower right of its image, and cover them appropriately as the slider moves, and then it'll be clear which framework the current image (or portion of it) belongs to.
Hey Tom, I'm the creator. They're actually even worse than what you're describing. On touchscreens, the handle slides up and down as you try to move it left or right. Horrible, isn't it? One of these days, I'll get around to fixing it. The only reason it hasn't been done yet is that, to be perfectly honest, you're the first one to give this feedback. So I appreciate it!
