ClickMend

ClickMend is a click-to-heal raid frame addon for WoW: Forever, built from the ground up for the modern client's addon rules, where VuhDo, Grid and Cell no longer work.

It replaces your party and raid frames with customizable health bars and lets you bind healing spells directly to mouse clicks on them: left click one heal, right click another, hold Shift, Ctrl or Alt for more, and scroll the mouse wheel for still more. Each class starts with a sensible set of heals, dispels and utility spells already assigned, and a grid-style options window lets you change any of them by typing a spell name. Cast target-free: no clicking a player first, no macros.

Frames can be sorted so tanks sit at the top of each group by default (sorted by HP, so not a flawless system yet). They also switch to a solid colour when a player has a debuff you can dispel, with each debuff type in its own colour, and which you can set yourself. Incoming heals, absorbs, mana, aggro, range and dead or offline states are all visible at a glance, and party and raid pets get their own frames with the same bindings.

Everything from frame size and layout to colours and click assignments is adjustable in game through sliders, checkboxes and a colour picker, or by editing a plain text config file
