UPDATE: Development of the product catalogue is, for now, complete. Anyone interested is welcome to read the updates below, and also visit the demo, linked below. It’s now as complete as I want/need it for the client I made it for.
I’ve had some questions here and direct, so I’ll address them here for clarity.
1. Will I be making it available for Rapidweaver/Stacks? Yes and no. Will I wrap it in a nice container that can be dragged and dropped into RW/Stacks? No. I have neither the skill nor inclination to do that. If a dev wants to work with me and do it, I’m open. But I won’t be doing it on my own. I will, though, make it available as a self-install system at some point. This will require you to FTP some files to your server and add code snippets/widgets to your page builder (it will be platform-independent). When will I do this? Early next year at some point. And no, it won’t be free.
2. Will I be turning it into an only store? Yes. 100% yes. I presently run quite a few online stores for clients using a customised version of PHP Jabber StivaStore. But nowadays, that script and PHPJ themselves are pretty shite (since the takeover), so I plan to evolve my system to replace it. I’m not yet sure if the one system will do both, or if the store will be a separate version. I suspect the latter, as my aim is to keep things as lightweight and simple as possible. Will I make this available? Yes, but it’ll be a licensed product with an upfront cost. When? Mid to late 2026 i suspect. That’s real-world schedulling, not the RW world version 
3. Am I going to adapt it for a blog for the RW/Stacks? Yes, that’s the project I’m starting today. Will I be making it available? Only if @Jannis doesn’t bring his product to the market. Jannis has been a long-time supporter of the RW/Stacks community (not to mention a great resource of help over the years) and I’m not going to release something that treads on his toes. Initially, I’ll be using it myself to replace Alloy.
Hope that covers it. I realise this is of little interest to most, so I won’t be doing further updates here.
I can’t give you a link to a demo as yet, as I’ve not added any security to the admin page, but I have made a video explaining it all.
In sort, it’s a super simple flat-file product catalogue. Think of it as an online store, without the ability to actually sell anything. I’ve built it for a particular client need, but it might be useful to others.
I might, most likely will, add a cart system to it at a later date, but right now, it’s only for displaying products.
It is demo’d in RapidWeaver, but it’s platform-independent. You could add it to any site. Whatever platform you use, you only need to add two pages: the main page and a product page. The entire system consists of three pages: main product listing page, the individual product page, and the admin page.
Have a look at the video: Bit long: 20mins, but there is quite a lot to demo.
Happy to answer any questions or take onboard any advice anyone wants to give.
