Simple Action Sets 0.70beta by Brodrick (aka Kirov)

Someone has taken over this project on Curse, please head there for updates.
(sorry for the off site link Cairenn)

Overview
Save action bars as sets that can be swapped out.

Description
Do you find yourself reshuffling your spells around on your action bars when ever you PvP or PvE? Are you finding that you have a custom main bar with 48 spells in it and 6 side bars and still need more buttons to hold all your spells, items and macros? Have some special case spells or macros setup you wish you didn't have to keep dragging on and off your action bar?

This addon will save all 120 actions, or just 1, and anywhere inbetween and let you swap them in at any time.

Features

• Save actions in to sets. Save all 120, or just 1.
• Swap those sets out at any time through a UI, dropdown menu, or macro.
• Save new sets directly from your action bars, alter those sets independant of the default UI, or create them from scratch. Spells, macros, items, even dragged from the action bars, can be dropped in to the Simple Action Sets setup frame actions.
• Action sets can swap out up to all 120 actions regardless of the bar mods used.
• If the player doesn't have an item at the time they swap in a set that includes it, automatically add the item to the bar when the player gets more (if the action button hasn't been used by that time).
• Titan Panel support.

Planned Features

• Better support for mutliple macros with the same name and texture.
• Allow per-action button control of clearing the current action bar when swapping (currently just an all or nothing feature).
• Setup auto switching for pally auras, druid forms, and rogue stealth.
• Access to sets saved to other characters on the same account.
• More informative help file, possibly with diagrams!
• Some method of transfering action sets through WoW to allow trading of action setups.
• superlative - Proper pickup / drop sounds for items.

Known Issues

• If you have a multiple macros with the same name and texture when the set is saved directly from the action bars it will use the macro that was created first for all of those macros. They can be changed in the setup for the correct ones, but swapping two macros on the same button with the same name and texture will not cause a swap.
