I wrote this addon, because I didn't like PallyPower. My addon gives you more control over the buffs, as you choose blessings unit based not class based.

Compared to PallyPower

Pros:

It counts as unit frame, so you can use mouse over macros
You can see how much time an unit has left from a specific buff
You can target the unit with middle click

Cons:

The frame can be bigger than PallyPower (customizable)
Not possible to set who-uses-what, instead it is automatically determined by the addon

Choosing which buff will be cast with left and right clicks:

If already has a buff (or one expired) from the player then that will be used on left click
If unit name has specific blessing priority set up then that will be used on left and right click
Class priority will be used on left and right click

Note

When a unit has a Blessing from another paladin that will be skipped (hence the priority).

Example

Paladin A casts Blessing of Kings on player P, then Paladin B wants to use the addon, because P has already has Kings, Blessing of Wisdom will be used instead (this is based on the default priority, which can be changed).

Frame

The units consists of 4 part:

Left icon: The Blessing that will be cast with left click
Right icon: The Blessing that will be cast with right click
Name in the middle (maximum characters can be specified in the settings)
Time left from the Blessing on the right

Note

The icon is split into two parts to save space, instead of showing two full icons. Check the images for an example.
