transposition and key changes

It would be nice to have a "key" marker. Just the same way as there is a meter marker,, a key marker would be great.
I have a song in the key of C minor. Then, a key change going half a step up. When transposing to different keys, I end up with a mix of chords with sharps and flats (because iReal still consider the key change section as the same key that was set for the whole song). Being able to set a different key in the middle of the song would solve that issue. I hate to read chords progression such as Gb-7 B7 EMaj7. It would be much better to have F#-7 B7 EMaj7.

There has been a lot of discussion on this topic.
