Think less developer more end user.
You are on to a good thing here keep it up. I haven't programmed since C64 and Basic but forced to since I've been tasked with making sense of 10gig of some messy PP and PM SAP data. Access and Excel just don't cut it. I've been on it for 2 months SOLID and won't go back to the usual Microsoft solutions for anything over a gig of data because this is perfect but you need to shorten this learning curve. My bosses are on my back. I love the low level flexibility but it would be nice to have high level layers to peel away when customisation is needed.
This is a tool kit for the average business analyst but under the covers so much more. USB mountable, no installation, 5 system files or less for easy installation but also expandable if needed.
It is all there already, Bring it together and tighten it up.
More menu options, throw in scripts,
Keep it up.
