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!
I also had a lot of trouble figuring out which side was supposed to be which.
Don't even have a button. Just put both items next to each other.
I'd like to imagine I know which of each example were better designed, but the handle going to the side opposite from the label was making me second guess. Move handle away from the label to reveal is how I took it, so hope that's what you intended.
OTOH, I'm on touch screen (iPad/iOS26/WebKit) and it didn't go up and down, it went side to side.
As other feedback, the dumpster fire and deprecation warnings in the docs make me want to try this. I find builder-to-builder candor refreshingly helpful, treating your doc reader like an actual partner instead of like a euphemism. Appreciate your same candor throughout these comments.
Chainlift > Agency Services > Team menu option seems inert.
I'm not on LinkedIn all that much but I'm there.
If you got rid of the slider entirely and just had it flick between the two images instantly, the entire handle business would become irrelevant, and you'd never need to think about it again!
I admit I don't do web stuff, so perhaps this is hard to do. But I think it's the ideal. Before/after comparisons are very easy to assess if you can flick between the two cases and let your eyes show you the differences. The value of having an image that's part one and part the other (and two completely separate parts!) seems a bit questionable.
(My line of work means I'm unlikely to end up a customer, so you don't have to pay attention to my opinions.)
