Numeration is minimalistic damage and healing meter.

It aims to be as memory and cpu efficient as possible for the data it stores. You can watch a really old version of it in action here: http:www.youtube.com/watch?v=f_yoYs0teSo. The code has been rewritten a lot since then, but the appearance did not change too much.

Features

Available Modes are: Damage, Damage Targets, Damage Taken: Targets, Damage Taken: Abilities, Friendly Fire, Healing + Absorb, Overhealing, Dispels, Interrupts, Power Gains and Deathlog
Powerful Deathlog overview shows who died (defense buffs, input heals, debuffs will also be displayed) and was combat-rezzed in chronological order for every fight-segment.
Every Mode can be completely disabled, but you have to edit a lua file for that
Records fights and stores them as segments (keeps optionally only bosses. Supported: Pandaria dungeon and raid/world bosses)
Automatic pop-up reset while entering a new instance
On the fly toggle for merging of pets /w owners
Report (no gui elements for this yet so top 9 are always being reported, except you report by clicking with the middle button on one of the bars, then all lines up to the selected bar are being reported)
Automatically hides in battleground/arena if "Record Only In Instances" is activated
Always shows the current segment that is being viewed in the titlebar ("O" = Overall, "C" = Current or a Number for the segmentnumber)
If a bar represents a spell, the tooltip of the spell is shown upon mouseovering the bar

Not Supported and probably won't be included in the future

Multiple windows with different views/modes
Spell Details like hits/crits/misses/(partial) resists and so on

Navigation

The navigation system is mainly inspired by Assessment, which is also used by the Skada Damage Meter addon. The basic idea:

Left-click: get more detailed information about the content of the bar under the mouse
Right-click: go back to the previous layer

The first layer of navigation shows all fight-segments to choose from (also "overall" and "current fight"), leftclick one to view all available Modes. After choosing a Mode by leftclicking it, you can see the first overview. Left-clicking further will give you more information about the selected item as long as there is something else available. Right-clicking anywhere will bring you back to the previous layer. You can always go back directly to the segment-selection layer by clicking on the "current viewed segment indicator" in the topright corner of the window.

Scrolling is done with the mousewheel.
To move the window: click&drag the left mousebutton while pressing the alt-key.
To open the dropdown menu: just click the arrow-thingie in the topright corner of the window.

Appearance customization

Unfortunately none of the options to customize the appearance of the main window can be found ingame. They are only available to you if you know how to use an editor to open the Config.lua file, found in the addon folder. I think every option there should be pretty much self-explanatory. And in case you where wondering why nothing happens when you change the "pos" option in that file: Once you used alt+leftclick drag to move the window, the coordinates are being read from the savedvariables. In order to use the ones in this file again, you have to delete the character-specific savedvariables for Numeration or use chat commnad "/run NumerationCharOptions.x = nil NumerationCharOptions.y = nil NumerationFrame:SetUserPlaced(false)" and reload after it.

Obviously i'm trying to improve it even further, so if you have any bug reports or suggestions, post away, but no promises on implementing features fast (or at all if I don't like them ).
