OzRaid is a raid/party window 'construction kit', designed to let you build clickable showing health/mana/buffs/debuffs/etc. for raid members and or targetted mobs.
Unlike other mods, this lets you build custom windows depending on what information you need only. For example, a raid leader may want to see the whole raids health status along with the major buffs (AB, Fort, Pink paw, etc.) so they can see at a glance if everyone is buffed & ready. Healers can show certain groups or classes (or the CT/oRA2 Main Tanks) on special big bars that only show current HoTs & debuffs, with the health deficit shown in the new 'Big K' numbers that show you quickly & easily what size heal to use. DPS'ers can make a replacement for the default 'Main Tanks Target' window, which will not only show raid icons (very useful for targetting when the raid leader is shouting 'kill the orange' in a mass of mobs), but also can be customised to show only the debuffs you care about - such as Curse of Elements, Sunders etc.
You can even make non-clickable info windows, for example all the raid members within 30 yards who are in groups 2 & 4 who dont have your class buff. These let you make reminders that will pop up if anyone in your assigned groups requires a rebuff & they are in range. There are too many different combinations to list, so the best thing to do is start with a preset and play with all the options till you work out what you want!
Basically, for each window you can specify the input units (i.e. my party, the raid, targetted mobs, Main Tanks, etc.) and then apply filters (hide based on class, group, etc.) Finally pick the display options that suit you, and which buffs/debuffs you want to see on the bars. Simple!
Fully compatable with Clique & other click-to-cast mods that use Cladhaire's system for registering clickable windows, so I reccomend using these for click-cast decursing & the like!
Frequently Asked Questions:

'I made a window but I cant click on the bars!' With patch 2.0, Blizzard forces any 'clickable' window to be locked during combat. What this means is the unit ID for a bar cannot change in combat. So, if you have selected any option in the OzRaid options that would require the units to change (i.e. filtering or sorting out people based on range, health status). These options are still there after 2.0 so you can make info windows such as an emergency monitor, but unfortunately this means you cannot click to target or cast.
'So.. isn't it like CT Raid Assist?' No. All it does is show unit health/mana bars (and raidicons, buffs etc.). It doesnt provide any of the other cool things CT does (like boss warnings, and many more) This addon was written simply to provide a smaller & neater overview of the raid than the CTRaid and Blizzard party frames. But it now does so much more. It also works in parties & solo as well as raids ;)
