I collapsed your separate posts into one (even though this possibly includes multiple add-ons at this point) – because they are reading more like vague self-promotion than anything else. If you want to publish your add-ons here (i.e. to use this space to support users), you can do that, but you need to focus on what users need to know. At a minimum, you need a useful brief title that includes the name of the add-on, and clear information (or a link) about where users can get the add-on.
