I'm trying to create a Plugin to transform WordPress as a CMS for a client. I'm using Posts with different Categories for different purposes.
What I want to do is customize my Post List Layout through my Plugin.
I've been searching everywhere for this type of implementation but I cannot find it.
My question is how can I do this without editing WordPress core.
I'm trying to do this trough Filters and Actions.
Does anyone knows what are the necessary Hooks to filter posts by Categories and change Post list columns ?
