Description:

Add two of my projects, use smaller images for labels (no need to download bigger ones).

Outdated description:

"Sponsorware" label added. Not sure if this is the best word ("commercial") to describe the projects I added. I might change it to "Sponsorware" directly since this is the only type of "paid" projects I know in the MkDocs ecosystem.

Also not sure about the image for the label: currently it's a dollar bill. I don't think it does justice to the sponsorware model, but I can't find any other relevant icon. Maybe something more like an "exchange"? Or a red heart ❤️ 🤷‍♂️? A heart and a lock?

Note: I'm also OK to just list such projects without a particular label 🤷

Checklist:

• I have read the CONTRIBUTING guidelines.
• I have not modified the README.md file. Projects are only supposed to be added or updated within the projects.yaml file since the README.md file is automatically generated.

@squidfunk how do you feel about this? Should our sponsorware projects have a "sponsorware" label attached in the form of a "dollar bill" (or similar) image? Or do we just drop the label and let users find out? It's not super visible or explanatory anyway, and currently there's no tooltip on hover.

I'm not sure it's a good idea to add a Sponsorware label to Material for MkDocs, because the entire project is not under Sponsorware, only Insiders, but for Sponsorware-only projects I think it makes sense, e.g., if our Sponsorware plugins would be listed ☺️

Yeah I see what you mean. Same for mkdocstrings and the ecosystem around it. Some projects are entirely exclusive to sponsors, some have both public and private features. Hard to explain that with a label. I think I'll just drop the label and add my projects directly. Anyone is free to raise their concerns, and I'll revise.
