A feature of the Visual Basic IDEs I find very useful is that once a variable/function is declared, any time I type its name it is automatically coerced into the same capitalisation. If I change the capitalisation in the declaration, all the instances of the name track. In VB I exploit that to ensure I have typed the name correctly. I realise b4a colours unknowns in red, but it would still be handy. Clearly the b4a editor is already aware of declarations on the run, so this should be fairly straightforward to do.
