RE: USE OUR BETA | beta.steempeak.com

Many animations are explained in a video I found.

No need to watch it all.

There is dragging down at minute 8:30, where you open a message and then drag to close it.
A similar one is explained around 14:50 where things expand and contract by dragging.
16:42 there's zooming in and out to change the grid size and amount of grid items.
18:42, an not so Steem-compatible example on how to leverage content and comments in a space-efficient way by scrolling the comments above the media content.
26:48, long-press to collapse comment tree.
30:00, explanation of the problems regarding the mobile markdown editor and space management.
30:52 the solution to space management (markdown wysiwyg)
37:18 flick content to dismiss it
43:22 drag a comment to the right to reply to it (you could also implement other gestures for voting)

Other gestures not explained in the video are: If you click a post, you can drag left from the post to go back to the list of posts, or drag right to go to the next post in the list. If you drag up, you see a menu with a left button to go back to the list. Drag up and down and you simply see more of the content. Alternatively, if you drag from the left side of the screen, you can drag a menu into the screen where you find the app's menu (day/dark mode, replies, profile, communities, trending, etc.).

Etc. Gestures are basically the charm of mobile, but they're hard to implement sometimes. Not pleasurable if you're hurrying to implement more features for the desktop version of the app.

Here's a link to Reddit's introduction of their own app (not the same one as on the 1st video).

There are no gestures displayed in this video, but it gives insight about the challenges of making their app.

If you want to explore more gestures, download the app Joey and Reddit's official app. Both have different gesture combinations that give a nice experience, although they are fewer gestures than what were introduced in the first video.
