Hi,
I strongly agree with Anthony. IMO, the formatter functionality is not intuitive, not well documented, and not well organized. I made a few suggestions for improvements in this posting: Observations and Proposals for the Wappler UI but have not received any response yet.
One of the suggestions was to use a UI similar to the one used to create conditions in a server action database query. The UI used there is much better than the one used by the formatter and the Wappler team is already maintaining that code. I would still polish it a bit further, making the fields for the operands larger, and organizing the operators differently (e.g., as proposed in the posting above) but the basics for a better UI are already there.
Hope this helps,
Alex
