Describe the solution you'd like

an option to retain the scale factor and scrolling position after a reload. I use Plash to display sites like dribbble, it would be most useful to display only the content without the site navigations.

That's a good idea. By scale factor, do you mean right-clicking in browsing mode and selecting "Zoom In"?

[mediter]

yes. Also maybe support for pinch/spread gesture

[sindresorhus]

I don't think there's any way to preserve the pinch zoom, but I'll look into it.

In the meantime, you could remove the navigation with CSS: #1 (comment)

• Preserve zoom state. de84110
• Preserve scroll state. This will require proper communication between JS and Swift as we need to inject a JS scroll listener and then send the scroll position back to Swift:

• Preserve pinch zoom state. Ideas welcome!

I don't intend to work on 2 and 3 anytime soon, so help welcome if anyone wants to see those happen.

Maybe we could use https://developer.apple.com/documentation/webkit/wkwebview/3752236-interactionstate?changes=__7 for this.

I added a tip to the readme on how to set a specific scroll position: https://github.com/sindresorhus/Plash#scroll-to-position
