"I thought I should share the current WYSYWYG filter configurations I've been using (work in progress)":

Here is the full list of modules we are using to make wysiwyg work. Some are optional, depending on your workflows and conifigurations.
If you want to just go for it, here is the drush command you can run to download everything:
