As of 1.12, thanks entirely to Shog9's efforts, this now works on Firefox as well as Chrome!

Description:

Provides a fully functional top bar, including realtime notifications, easy chat server switching, and fast room list searching, at the top of all chat rooms. Keep tabs on your inbox and site activity while chatting.

Can also match the chat room's theme:

And now contains a fancy new room finder dropdown:

Features:

• Fully functional with dropdowns and realtime notifications.

• Topbar background can match chat room theme.

• Adds a dropdown that lets you search for rooms directly (with optional search-as-you-type support and the ability to open rooms in the same tab or a new one).

• Adds chat server links to SE dropdown (click server name to open in new window, click "switch" to open in same window), with optional auto-rejoin favorite rooms. Makes using multiple chat servers convenient:

  

• Does not require additional authentication or access tokens.

• To configure settings, click the "topbar" link in the footer:

  

Console Usage:

Some options are settable through the console via the ChatTopBar object. All options set will be saved. The following console commands are available:

• ChatTopBar.setWiden(boolean): True to use wide layout, false to use default width.
• ChatTopBar.setThemed(boolean): True to make the topbar match the current chat room's theme, false to use the default dark background.
• ChatTopBar.setBrightness(float): Set brightness of icons and text in topbar (1.0 is default). This setting is saved per theme, and is only applied when themes are enabled. Can help deal with themes that don't contrast well with the icons.
• ChatTopBar.setQuiet(boolean): True to suppress console output.
• ChatTopBar.setShowSwitcher(boolean): True to show chat server links in SE dropdown.
• ChatTopBar.setRejoinOnSwitch(boolean): True to make "switch" links in SE dropdown auto-rejoin favorite rooms.
• ChatTopBar.setOpenRoomsHere(boolean): True to open rooms from the room search dropdown in this tab, false to open them in a new tab.
• ChatTopBar.setAutoSearch(boolean): True to search for rooms in the room finder as you type, false to require you to press a search button.
• ChatTopBar.setSearchByActivity(boolean): True to sort room search by activity, false to sort by number of people in room.
• ChatTopBar.setRunInFrame(boolean): True to allow the topbar to load when chat is in an iframe, false not to. For compatibility with other scripts.
• ChatTopBar.showChangeLog(): Show the change log dialog.
• ChatTopBar.forgetAccount(): Forget cached network account ID, useful for testing.
• ChatTopBar.forgetEverything(): Erase all persistent settings, useful for testing.
• ChatTopBar.dumpSettings(): Print all persistent settings, useful for testing.
• ChatTopBar.fakeUnreadCounts(inbox,rep): Fake unread item messages to show indicators, useful for testing and photo ops.

All of the set* functions can be run with no parameters to return the current setting.

Notes:

• Uses one API query to get account ID. However, this value is cached, so usage should be extremely minimal. This is the only thing it uses the API for, so your quota should be safe.
• Mad props to Gerry and Shog9 for helping me figure stuff out.

Issues:

• Initial state of notification / reputation unread counts may be inaccurate due to fundamental issues with the topbar on chat.
• You may post bugs and requests here or on Github (or ping me in The Tavern)!

  • Clicking "switch" on chat server link automatically rejoins favorite rooms (can be disabled in settings).
  • Brightness setting is now associated with the current room's theme rather than the room itself (so it applies to all rooms with the same theme). Apologies for any reset settings (it does make a good attempt to copy them, though).
