Version 0.3.24
Added handling of GFAQs board-specific links - clicking a link inside of
a topic that leads to a board, topic, etc. will now open in-app. Let me
know of any links that don't get opened in-app that should be.
Changing accounts will now finish on the last page previously loaded.
History is wiped, however, so pressing back immediately after changing
accounts will close the app.
Replaced pull-to-refresh library. New library fixes various issues the
old deprecated library had with overscrolling sometimes getting stuck.
New PTR library also replaces the network activity icon and progress
bars obey accent color theming. Does not support pull from bottom.
Replaced "Open in Browser" button with "Copy Current Page URL" button
Moved Global Custom Signature setting up into the Accounts category
Fixed bug where clicking on a link, pressing back, then clicking on a
different link in the same message acts as if you clicked on the first
link again
Fixed various bugs caused by change in login form layout
Possible fix for issue where post interface content gets erased if the
app loses focus
