Feeds for me. I got it from Joe to look at possibilities for hooking in Charter to the data sources but although that doesn’t look possible i got to playing with it anyway and it really is great. Allows you to pull dynamic data into templates that you build in RW/Stacks. The data can be held in numerous sources (csv, json, databases etc).
I even added support for Feeds in the 3 Source grid stacks (Grid, Grid Plus and Grid Plus Pro) and in Splider 2. This means that you can add Feeds stack directly inside any of these, create a template for a single grid item / slide and then Feeds will auto-generate these things for every entry in the attached data source. The possibilities of this are endless.
I am actually putting the finishing touches to a Source/Feeds demo project to demo all of this so stay tuned for that!
p.s. I now use Feeds to power the stacks and bundles section on my main stacks page. From the single csv file that this page is attached to i can add new stacks, new bundles, apply coupon codes and add in notices about special deals etc. Amazing!
