Hi, thank you for this post. I will address each of these items:
1. Based on this edit and snippets of senior editor/staff messages from the PCGW Discord, the monetization section should remain to reflect the taxonomy given in the infobox. Most articles missing this section existed before it was introduced in 2020, and the articles created since now include it by default. I agree that it is not that necessary for some pages, but including it anyway seems to be the chosen approach.
2. Makes sense, looks like I missed this. Most references either paste the entire page browser tab title or just use the article name, and this was the convention I was personally following. But I agree, it would be more descriptive to add the website name to the reference when it's not already given.
3. The letter X is used across the wiki for display resolution listings, multipliers for graphical features like anisotropic filtering, etc. The editing guide Video page and the anisotropic filtering glossary page are examples of this. If I had to guess, PCGW takes this approach because it is simpler to type for entry-level editors.
4. I do not see the benefit in making this change. The HTTP/HTTPS protocols are re-added to the URL when other archived pages are visited on the Wayback Machine, and virtually all other Wayback Machine citations on the wiki include the protocols as well. It is strange to deviate from this convention for just a single page, as most editors just copy and paste the Wayback Machine URLs as-is.
5. "d3d8to9" is the name designated by the author, so that is the name we should use. Various existing pages mentioning the wrapper, such as the display wrapper glossary page, already do this. It could be argued that crosire intended for the wrapper's title to refer to the Direct3D 8 DLL filename (d3d8.dll), which has been traditionally lowercase throughout releases of Windows and legacy DirectX redistributables, but that is uncertain. Ultimately, seeing that d3d8to9 itself is an unofficial library, these corrections don't really apply.
The main reason why I reverted these changes is because they were not consistent with the stylization of most other pages on the wiki. However, I am glad to see that someone else cares about this as much as I do, as logical and consistent stylization is critical to page presentation and maintenance. The editing guide is my primary source for this information, and it needs to be updated - I have brought this up several times on the PCGW Discord after editing disputes over things that should be in the guide but aren't, but little progress has been made. Hopefully, this will change in due time.
