Before I start my review of Skada, I wanted to thank the support I've been getting from friends and the ladies over at WoW_Ladies on Live Journal. I appreciate it quite a bit and it's my encouragement to try and keep this up. Additionally, I'll be willing evaluate your UI if you send me an email including at least two screenshots of your UI (one in combat and one out would probably be best). I'll be honest in my critique of it, but I will try to offer advice on where I feel you can improve. If you want me to, please send me an email with two screenshots, your name (character name is fine), and what you're trying to do with your UI the way it is and if you're looking for specific things to be changed. Send that to caelys@gmail.com.
What is Skada?
Skada Damage Meters is.. well it's a damage meter, which I hope you managed to figure out on your own. One of the biggest differences between Skada and the ever popular Recount, is it's not a memory hog. In Vault of Archavon, Recount uses around 10-20MiB for all the data it's storing. Skada, by comparison in the same raid setting, uses 1.7MiB.
Again, I don't claim to know anything about .lua files, but my understanding of damage meters is that it basically converts everything that's going through your combat log and parses it into a more graphical or visual form.
What makes it different from Recount?
As I said before, it's not a memory hog - which is great for those of us who play on laptops or on a computer that is slightly outdated. Lowering the amount of memory your addons as a whole are using should improve your frame rate and potentially game play (if you play with a very low fps or high latency).
There are, however, three features to Skada that I think sets it apart from Recount; Absorbs Meters, multiple window capabilities and its Combat Mode Switching.
