Next step: add recognition for foreign partition formats like HFS+ and ext4. Just recognition would be a great step, something along the lines of: hey we see there are partitions on this disk; are you sure you want to format this? This instead of: Do you want to format this disk?

I don't even expect that you can read or write to those partitions, which of course would be trivial to add for them. Just recognition would be great!
