SavedInstances

An addon that keeps track of the instance/raid lockouts saved against your characters, and related currencies and cooldowns. SavedInstances has the following features:

Tooltip display shows current lockouts and data for all your characters, and optionally expired lockouts
Secondary tooltip (per-lockout) shows lockout details including bosses available, lock status and time remaining, and can be linked into chat

Tracks seals, resources, money, and other useful currencies (configurable display)
Tracks weekly World Boss Loots
Tracks LFR bosses looted
Tracks holiday boss encounters

Tracks Tanaan Jungle oil bosses: Doomroller, Deathtalon, Terrorfist, Vengeance (mouseover daily quests)
Tracks Garrison invasion rewards (mouseover weekly quests)
Tracks monthly Darkmoon Faire quests completed for each toon (mouseover weekly quests)
Tracks weekly "special" loots on the Timeless Isle and Isle of Thunder (mouseover weekly quests)
Tracks trade skill cooldowns (eg. Celestial cloth, Living Steel transmute, Secrets of Draenor, etc.)
Tracks data for all your characters across servers and factions

Known Issues

SavedInstances is pretty good, but it's still not quite perfect. There are currently a few issues:

When first installed, SavedInstances has no knowledge of your other characters: you'll need to log into each for their information to be recorded
(*) = Indicates a feature displaying data that cannot be directly queried from the server, but rather is collected by the addon while observing player actions. Actions taken while the addon is disabled, or from other computers, or before a client crash, can result in this display being temporarily out-of-date or incomplete.
Lockout time remaining and other features may be off by an hour when your region changes to and from Daylight Savings Time, or if you manually adjust the timezone of your computer.
Tracking for the 10 instance per hour limit uses heuristic detection and hence may occasionally be inaccurate (notably when another player has lead and performs explicit resets), but does a reasonable job for common cases.

Usage

SavedInstances will create a new button on the minimap, and you can use it to interact with SavedInstances just fine. The addon can also be displayed using a LibDataBroker-compatible display addon. I personally use Chocolate Bar which works quite well. Finally, you can bind a key or use "/si show" to open a detached window containing the display.
