Look at what we are doing here. Instead of me trying to use words to describe the software I am looking for, WHAT IF I made a simulation of the software I am looking for … that you could play with to know just what I'm looking for?
That's the software I'm looking for. I'd SHOW YOU but …
This may be in the family of Rapid Application Development (RAD), however there seems to be a sub class of these known as "Low Code development tools" … which actually develop working apps and forms. This, however, would be the wrong focus. Low code tools sacrifice flexibility for functionality.
The software I am looking for removes functionality in order to be more flexible.
And if flexibility comes through minimal coding (scripting?) then that would work.
Mockplus is a very interesting offering, and I think is close … however it seems rather widget-based. In other words, your GUI simulation looks like their widgets.
The software I am looking for would have to be very flexible in the STYLE aspects of a GUI … where the ability to appear like anything, and behave like anything is the right direction … from crazy animated glowing light things to super futuristic HUD-like elements. Very strong, explicit control of graphics elements a must (like controlling the alpha for any design element).
