Features

Extended in app navigation: opening links to journals now displays them within the app. Journals feature the same controls (including comments) as submissions, except the Download and Favorite controls.
New "Notifications" tab: this lists all submission comment and journal notifications from https://www.furaffinity.net/msg/others/ and lets you jump to the corresponding submission or journal from there.
The "Notifications" screen provides a control in top right to nuke all submission comment or journal notifications.
Draft comments on the current submission or journal are saved until posted. So you can freely go back and check the submission or journal details before continuing your own comment. Leaving the submission or journal will discard the draft.
The comment editor now displays the comment you're answering to.

Misc

Pages now display a progress indicator instead of staying empty while waiting for furaffinity.net servers to provide the target web page.
The Submissions tab will not automatically refresh anymore if it's not currently displayed (eg. you're on another tab or have opened some submission). This prevents scrolling away from your last seen submission in the feed.

Links to pages that were supported for in app navigation now also work from comments.
Fix a "loading failed" message appearing when a user whose name contains special characters is involved in the target page.
