I would appreciate if we could import/export binary *.bin files from system to ROM and RAM modules instead of writing them line by line
Actually, you can already do this, but not quite like what you want. You can copy its content using the copy button on the menu when editing ROM, and write the data with a paste button. The format of what gets copied and accepted is a number separated by a newline. (You need to choose the right format. e.g., Unsigned Binary, Decimal, etc.)
