The author used to at least actively solicit feedback, I never once noticed acknowledgement of any of it though.
User suggestions and bug reports are promptly followed up on. There are almost no known errors at this point, so it is very good shape.
You are correct that it has elements of JavaScript, but that is inevitable given that the primary output of the transpiler is JS code for use on the web, so some JS functions have to be present for that to work, and to inter-operate with JS, one has to use their string system.
The attempt to offer an integrated programming system, where we return to the simplicity of VB6, or Borland Delphi, is actually quite ambitious, as in order to offer such an integrated product one has to build in a database (graph in this case), a layout engine (novel, Renaissance proportion based layout model), a drawing system, and a way of coordinating between client/server (a novel subscription to a single source of truth system, with remote procedure calls).
The language is primarily based on Modula-2, which the author of Beads used for 20 years quite successfully in large commercial products. There is nothing from COBOL or Ada that i can think of (although Prof. Wirth did contribute to Ada I believe), not sure what the M language is. There are some elements of PROLOG built in that are not readily apparent, as the core programming pattern is State-Action-Model (see sam.js.org), and if you change a state variable, then any drawing code that used that variable is scheduled for refresh.
I don't see why this is true (i also don't see it as a bad thing. Take what works and all that).
