Swipe up dock for all screen(currently works only in home screen) including apps, games. Customizable quick settings (add as many as user want or remove) and options to add media volume, ring volume, call volume and notification volume slider. And options to theme it. When added more than one line of quick settings, offer 2 types of swipe up. Option 1.with one swipe up it opens the present layout(apps +one line of quick settings. Then expand the quick settings part by a second swipe up. Or option 2.always open the dock quick settings expanded. Its incredibly helpful for the new bigger phones. But it has to function on every screen, be in games or apps or YouTube or outlook. Plus add the option to add not only quick settings but shortcuts, urls, system settings shortcuts. Here is a screenshot of the example. It's a third party indie app. So it's very much achievable by the awesome devs of Ms. Please check the photo and consider my idea. https://photos.app.goo.gl/fBPksVjXywvgUvUQ6

I used to think that keeping the dock available on all screens(in app, games, browsers anything) needs root access. But recently I came across one app called buttom quick setting. It makes the quick setting panel available on all screen but by swiping up from buttom edge. It also allows to rearrange, edit, remove, add quick settings but not limited to it, apps, url shortcuts, system settings shortcuts can be added as well. Plus it allows to keep volume, brightness (already present in ms launcher), ring volume, media volume and notification volume slider. Plus user can theme, multiple colors are available. If a small indie devoloper can do this, then Ms devs can do it even better. Please consider my idea, with big phones, this is kind of Godsend. Plus there is another feature, a gesture, user can control the brightness slider just by swiping extreme bottom of the screen, vertically. It's a paid app though, so may be you can give this as premium feature. Like me, a hundred thousand people will buy it if its reasonably priced. We love Ms, we remember how creative and extraordinary wp ui was. Anyway, thanks for reading.
