[WIP][v1.29.0] NOTIFICATIONS!

NOTIFICATIONS!

Welcome to the notifications update where I will attempt to add notifications support to the app.

But first, this coming release will add support for RedGifs. This means that any RedGif links will play within the app and not error out. In addition, the built-in video player is getting many more options in the overflow menu to match the options of images.

Changes so far:

• Added support for RedGifs.
• Added more options in the built-in video player.
• Changed the comment screen to auto focus the input field when first shown.
• Fixed an issue where custom comment gesture actions where not being applied.
• Fixed a regression with screenshot mode where post actions are not hidden when in screenshot mode.
• Fixed some inconsistent scrolling behavior throughout the app.
