What The Addon Accomplishes

I've used Danina's Shadow Timer addon for a while and liked it enough to tweak it for my own raiding use. Here's the gist of what I tried to solve. Credit has to go to Danina for the initial inspiration. https://legacy-wow.com/cata-addons/shadow-timers/

When should I refresh my DoTs. With all the proccs I never quite knew when the right time was to refresh a DoT, namely SW:P and VT. That's where this addon comes into play.

Most procs give you an amount of a stat for a duration. For instance, Volcanic Potion grants a buff called Volcanic Power which gives 1200 Int for 25 seconds. Moonwell Chalice gives an amount of Mastery for 12 seconds. You get the idea. So SPDT tells you to refresh your dots with procs. 20 seconds into a fight, procs feel random with no real way to discern if a proc is a DPS upgrade. What I've done is use HowToPriest.com BiS scaling numbers to convert a buff to it's Int equivalency and created what I refer to as a "buff score". As of 1.0c all of this data is configurable in the options panel under Blizzard's Interface-AddOns tab.

There are two bufftables. One that the user has to fill depending on his trinkets and upgraded versions, which can be managed via the ingame menu. The other bufftable is hidden and i call it class/standard buff table.

The class/standard buff table contains of the following buffs

(so you do not need to add them)

Heroism

Bloodlust

Time Warp

Primal Rage

Tricks of the Trade (via rogue)

Berserking

--Professions--

Synapse Spring

Lifeblood

Lightweave Embroidery

--Consumables--

Volcanic Potion

--Enchants--

Power Torrent

Hurricane

--priest abilities-

- Power Infusion

Dark Evangelism

Empowered Shadow

The key is that when you cast Devouring Plague or Vampiric Touch, the current buff score is copied to the top of the icon showing its cooldown. You can then use that number to figure out if refreshing a DoT would be a DPS increase or decrease. Of course, refreshing seconds before a proc wears off is always beneficial and therefore the icon will turn green. The buff score is not intended to be an accurate reflection of actual damage numbers. It's there so that you can judge the relative difference between when you first cast a DoT and your current buff level. Higher numbers recast. Lower numbers wait until you have to refresh it.

Commands

/spdt (toggle | move | reset | options | clear | scale [1-10]

Toggle: Show/Hide the addon.

reset: Used to recycle the display of the addon. Can help if there's a glitch in the display. 

move: Enables a frame around the addon's visible elements so that the entire frame can be positioned.

options: Displays the option panel in the Blizzard Interface Option screen. "/spdt" does the same

clear: Clears the internal mob list that tracks DoTs on multiple targets.

scale: sets the scale of the window, 6 is the default size

Ruled out Enhancements: 
Adding a timer for buff score - In practice I didn't find the information to be useful because when you added up the buffs, the score might change 5 times in less than a second making the velocity of the information useless in an already fast moving UI addon.
