OK, I have a feeling that this request is outside of the scope of what VA is for, but here goes.
An "Advanced mode". What I mean by this is the point and click interface for building commands is awesome, very easy to use, and you can do some pretty cool things with it. But it's not without limitations.
What I propose is a "scripting mode". Instead of the PaC interface, creating a new command via scripting just opens a text box. Within, the more programatically inclined among us can create our commands using some kind of scripting language.
Look at how RPG Maker MV implements it. You can create an awesome game using nothing but the map editor and database. BUT, if you want to go all out, pop open the Script window and go to Javascript town on your game.
This feature might make it easier to implement more advanced requested features, such as arrays, multi-condition If statements, Select Case, and the like. Features the average user would probably never use, but advanced users are biting at the bit for. This way would also make it easier by not having to figure out the best way to create a GUI for the new feature, just implement it in scripting mode and if the unwashed masses decide they do want it, then add a PaC version of the feature.
I LOVE VA, been using it since I got Elite:Dangerous (especially with EDDI), but some stuff (lack of arrays, having to use nested Ifs when comparing against multiple criteria, the painfully small "Write text to file" edit box) kinda puts a cramp in the ol' creative juice organ. Just my 2 cents, thanks!!!
