Return of Reckoning

Is there a good healing addon that will let you configure types of "clicks" onto a unit frame in order to cast your healing spells like vuhduh does in WOW? Currently, only way I can see in game is that you have to click on the frame, then hit your hotkey for wahtever spell. Not sure if the mod community has created healing addons for this game as of yet?

Try this addon

https://tools.idrinth.de/addons/enemy/

in the unit frame options you can bind skills activated by mouse click, mouse + shift, mouse + ctrl ...

you can google for some guide that explain how it works

I tried the Enemy addon, but I can't get it to (fully) work? The left click (+ modifiers) ability casting seems to work, but not for middle/right mouse button. Is there another/newer version of Enemy where this does work? Or perhaps a different addon?

What you talk about seems to be healgrid:

Main problem, out to date, some buff ID don't exist on latest ( 6-7y) version. You will need to update it by yourself.

If you can upload updated version , some healer will love ya a lot.
