It wouldn't need to extend the IDE memory view window, rather a menu option to dump out a region of memory.
Something like:
VAssistX -> Debug -> VA Memory Dump
Which opens a dialog with these fields:
Address: address_or_symbol_name
Size: unsigned_size_in_bytes
Destination: file_path
save_button
progress_bar
One of my use-cases is dealing with external image data. After the image is downloaded I'd like to extract parts of it from memory.
