Tiny suggestions about the Formula editor of new versions:
(1) Replace only selected portion (not just replace all).
(2) Autocomplete close brackets,
such as after the user presses ( then generate ) automatically,
also after the user presses { then generate } automatically.
(3) Provide keyboard events to move lines up or down,
for example, like the keyboard actions of Alt+up or down inside VsCode.
I don't know if the suggestions above are feasible in Formula Editor of AmiBroker but just provide my suggestions sincerely.
