Hi, When writing long posts in the forum with an iPad, I need to scroll up and down as I’m working on my post. However, the “scroll momentum” is disabled. So whenever I let go of my finger after swiping up or down, scrolling immediately stops. Instead, it should continue for 2-3 seconds after I stop. In particular, if I swipe quickly, it should go very far. I believe this is a simple CSS property gone wrong. Fixing this greatly improves usability with an iPad, when writing longer posts (which I do all the time). The iPad Pro is becoming a very popular device and outperformed Apple’s expectations in terms of sales. I expect this trend to continue. Thanks! ---

I am not seeing a repro of this on meta, could this be something custom with your CSS? Are you able to repro this here? ---

Oh, I see what this is, I did not read this properly. > [@littke](#): > > When **writing long posts** in the forum with an iPad Yes, this is a problem due to the way we implemented “preview sync”, definitely something we can improve for ultra long posts, I suspect it is fairly complex to fix though. It is way beyond a 1 line CSS fix we would need to handle gestures here I think. ---

Got it. Thanks! When combined with the “editor only takes up half the height of the page” issue that you and I are discussing in another thread, almost all of my posts qualify as “super long posts” since the textarea is so small 🙂 ---

Understood, I have a physical iPad keyboard and will experiment a bit to see if anything is better in iOS 12, stuff has changed here over the years, but its slow and Apple are not making any developers life easy here. ---

This is the most responsive support I think I’ve seen to date from a SaaS company. Bravo. ---

Have you tried out this button on the composer? ![image](https://global.discourse-cdn.com/meta/original/3X/2/b/2b2e2d6c0f24952a77794933c4070a12a4d10d06.png) I confirmed just now it works great on iPad + external keyboard. It provides a pretty excellent writing experience. ---

> [@sam](#): > > I confirmed just now it works great on iPad + external keyboard. It provides a pretty excellent writing experience Yes, it’s much better, thank you very much. It _is_ the mode I am using the video though. So, momentum scrolling is still an issue within the full-screen mode. With the following minor tweaks, I think it can work well: - Momentum scrolling fix - Remember full-screen mode after minimizing and reopening editor (it currently forgets it) - Respect the cursor position when tapping inside the textarea (it currently moves the cursor to the beginning of the text) - Ability to actually submit from this view And bonus: - Make the full-screen and minimize buttons somewhat larger (they’re a little hard to tap on mobile) - Ability to edit title of a new thread from within this mode - Somewhat larger font-size on iPad (or customizable somehow) Hope this helps!

> [@littke](#): > > Somewhat larger font-size on iPad (or customizable somehow) Very quick one here, everything you see on the screen is customizable, highly recommend you try out our `/admin/customize/themes` section, try creating a theme component, you can amend CSS for anything you want on your site. ---

@sam Did you say somewhere that momentum scrolling is now fixed? ---

No, this is going to be very tricky to work around, my priorities at the moment here are: 1. Start a movement to get Apple to provide an API that tells us that a keyboard is connected, Already opened a ticked with Apple on the bug tracker and Webkit, zero traction. 2. Decide with @codinghorror if we can pull in the “I have a keyboard” switch for iPads, instead of requiring a component 3. Figure our how to do shortcut post submission. Maybe make “option+enter” work for post submitting. 4. The touch resizing of composer may need a bit of tuning for touch, its a bit finicky 5. Maybe figure out cut and paste of images on iPad Momentum thing is not on my list for now ---

Super! I recommend CMD+Enter for submission, that seems to be the iOS standard. ---

这件事已经朝着很多方向发展了，@littke，你觉得我们还需要在这里做些什么吗？
