The :before technique for adding the icon was removed, because it
resulted in some rendering issues when the layout pressure in the
message bubble got too high - you would see a partial icon. This
solution shrinks the icon a bit when the filename wants to expand to
take its space.
The iOS bubble width also needed special care to ensure it didn't expand
to accommodate the very wide filenames. Beyond that, overflow: hidden
needed to be applied at several levels to make everything behave as
expected.
FREEBIE
- Last seen indicator now spans the full conversation, with subtle
shadow highlights above and below
- Scrollbars now overlap the content of the conversation, allowing last
seen indicator to touch the right edge of the window.
- The iOS and Android conversation background is now #eee instead of
white, which meant that the outgoing messages (Android) and incoming
messages (iOS) had to be updated for contrast. They now have white
backgrounds.
- Similarly, the scroll down button needed more contrast, and its
background is now white in light themes.
FREEBIE
This is to ensure that when there are a lot of unread messages, the user
is given the chance to see all of them by being scrolled to the oldest
new message.
When a new message comes in, the indicator will be incremented.
When the user sends a message or switches away from the conversation,
the last seen indicator will be removed.
